During your Washington vacation, don't miss these great establishments and attractions:

National Museum of Natural History
Before you step inside the museum, stop outside first, on the 9th Street side of the building, to visit the butterfly garden. Four habitats -- wetland, meadow, wood's edge, and urban garden -- are on view, designed to beckon butterflies and visitors alike. The garden is at its best in warm weather, but it's open year-round.Now go inside. Children refer to this Smithsonian showcase as "the dinosaur museum," since there's a dinosaur hall, or sometimes "the elephant museum," since a huge African bush elephant is the first thing you see if you enter from the Mall. Whatever you call it, the National Museum of Natural History is the largest of its kind in the world, and one of the most visited museums in Washington. It contains more than 124 million artifacts and specimens, everything from Ice Age mammoths to the legendary Hope Diamond. The same warning applies here as at the National Museum of American History: You're going to suffer artifact overload, so take a reasoned approach to sightseeing.If you have children, you might want to make your first stop the first-floor Discovery Room, which is filled with creative hands-on exhibits "for children of all ages." Call ahead or inquire at the information desk about hours. Also popular among little kids is the second floor's O. Orkin Insect Zoo , where they enjoy looking at tarantulas, centipedes, and the like, and crawling through a model of an African termite mound. The Natural History museum, like its sister Smithsonian museums, is struggling to overhaul and modernize its exhibits, some of which are quite dated in appearance, if not in the facts presented. So a renovation of the gems and minerals hall has made the Janet Annenberg Hooker Hall of Geology, Gems, and Minerals worth a stop. You can learn all you want about earth science, from volcanology to the importance of mining. Interactive computers, animated graphics, and a multimedia presentation of the "big picture" story of the earth are some of the things that have moved the exhibit and the museum a bit further into the 21st century.The Kenneth E. Behring Hall of Mammals is an example of an updated section of the museum. Here, visitors can operate interactive dioramas that explain how mammals evolved and adapted to changes in habitat and climate over the course of millions of years. At least 274 models of mammals and a dozen fossils are on display. This exhibit represents the first time the mammal hall has been updated since 1963. Also, don't miss African Voices Hall, which presents the people, cultures, and lives of Africa, through photos, videos, and more than 400 objects.Other Rotunda-level displays include the fossil collection, which traces evolution back billions of years and includes a 3.5-billion-year-old stromatolite (blue-green algae clump) fossil -- one of the earliest signs of life on Earth -- and a 70-million-year-old dinosaur egg. Life in the Ancient Seas features a 100-foot-long mural depicting primitive whales, a life-size walk-around diorama of a 230-million-year-old coral reef, and more than 2,000 fossils that chronicle the evolution of marine life. The Dinosaur Hall displays giant skeletons of creatures that dominated the earth for 140 million years before their extinction about 65 million years ago. Suspended from the ceiling over Dinosaur Hall are replicas of ancient birds, including a life-size model of the pterosaur, which had a 40-foot wingspan. Also residing above this hall is the jaw of an ancient shark, the Carcharodon megalodon, which lived in the oceans 5 million years ago. A monstrous 40-foot-long predator, with teeth 5 to 6 inches long, it could have consumed a Volkswagen Bug in one gulp. In an effort to update this exhibit, the museum in 2001 mounted a digital triceratops (that is, a computerized rendering of that dinosaur); you can manipulate the image to learn more about it.Don't miss the Discovery Center, funded by the Discovery Channel, featuring the Johnson IMAX theater with a six-story-high screen for 2-D and 3-D movies (T-Rex: Back to the Cretaceous was among those shown in 2004), a six-story Atrium Cafe with a food court, and expanded museum shops. The museum also offers the small Fossil Café, located within the dinosaur exhibit on the first floor. In this 50-seat cafe, the tables' clear plastic tops are actually fossil cases that present fossilized plants and insects for your inspection as you munch away on smoked turkey sandwiches, goat cheese quiche, and the like.The theater box office is on the first floor of the museum; purchase tickets as early as possible, or at least 30 minutes before the screening. The box office is open daily from 9:45am through the last show. Films are shown continuously throughout the day. Ticket prices are $8 for adults and $6.50 for children (2-12) and seniors 55 or older. On Friday nights from 6 to 10pm, the theater stages live jazz nights, starring excellent local musicians ($5 cover).

Marian Koshland Science Museum
The National Academy of Sciences operates this museum, which was conceived of by molecular biologist Daniel Koshland, in memory of his wife, the immunologist and molecular biologist, Marian Koshland, who died in 1997. The museum opened in April 2004 in the heart of downtown D.C. Recommended for children over 13, and especially for those with a scientific bent, the museum presents state-of-the-art exhibits that explore the complexities of science. Three exhibits currently on show are the Wonders of Science, which includes animations of groundbreaking research and an introductory film about the nature of science; Global Warming Facts and Our Future; and Putting DNA to Work, which covers the details of current approaches to DNA sequencing, from tracking the origins of SARS to criminal forensics.

Vietnam Veterans Memorial
The Vietnam Veterans Memorial is possibly the most poignant sight in Washington: two long, black-granite walls in the shape of a V, each inscribed with the names of the men and women who gave their lives, or remain missing, in the longest war in American history. Even if no one close to you died in Vietnam, it's wrenching to watch visitors grimly studying the directories to find out where their loved ones are listed, or rubbing pencil on paper held against a name etched into the wall. The walls list close to 60,000 people, many of whom died very young.Because of the raging conflict over U.S. involvement in the war, Vietnam veterans had received almost no recognition of their service before the memorial was conceived by Vietnam veteran Jan Scruggs. The nonprofit Vietnam Veterans Memorial Fund raised $7 million and secured a 2-acre site in tranquil Constitution Gardens to erect a memorial that would make no political statement about the war and would harmonize with neighboring memorials. By separating the issue of the wartime service of individuals from the issue of U.S. policy in Vietnam, the VVMF hoped to begin a process of national reconciliation.Yale senior Maya Lin's design was chosen in a national competition open to all citizens over 18 years of age. The two walls are angled at 125° to point to the Washington Monument and the Lincoln Memorial. The wall's mirrorlike surface reflects surrounding trees, lawns, and monuments. The names are inscribed in chronological order, documenting an epoch in American history as a series of individual sacrifices from the date of the first casualty in 1959. The National Park Service continues to add names over the years, of those Vietnam veterans who die eventually of injuries sustained during the war.The wall was erected in 1982. In 1984, a lifesize sculpture of three Vietnam soldiers by Frederick Hart was installed at the entrance plaza. Near the statue, a flag flies from a 60-foot staff. Another sculpture, the Vietnam Veterans Women's Memorial, which depicts three servicewomen tending a wounded soldier, was installed on Veterans Day 1993. You should allow about 20 to 30 minutes here.The park rangers at the Vietnam Veterans Memorial are very knowledgeable and are usually milling about -- be sure to seek them out if you have any questions. Limited parking is available along Constitution Avenue.

Embassy Suites Hotel Downtown
This hotel offers unbelievable value and a convenient location, within walking distance of Foggy Bottom, Georgetown, and Dupont Circle. You enter into a tropical and glassy eight-story atrium with two waterfalls constantly running. This is where you'll enjoy an ample complimentary breakfast -- not your standard cold croissant and coffee, but stations from which you can choose omelets made to order, waffles, bacon, fresh fruit, juices, bagels, and pastries. Tables are scattered in alcoves throughout the atrium to allow for privacy. Each evening, the atrium is the setting for complimentary beverages (including cocktails) and light cold snacks. The hotel's restaurant offers discounts to hotel guests and a children's menu for $4.95.By February 2005, the hotel will have completed a $4.5 million renovation to give the entire property an "urban-modern, but not chi-chi" look: Dark marble replaces light marble, guest room sofas will be covered in maroon tapestry fabric, and wireless Internet access will be available throughout the hotel (guests pay $9.95 per 24-hours for a computer access card, if needed).The accommodations remain, as always, nicer than your average hotel room, with better amenities. Every unit is a two-room suite, with a living room that closes off completely from the rest of the suite. The living room holds a queen-size sofa bed, TV, easy chair, and large table with four comfortable chairs around it. The bedroom lies at the back of the suite, overlooking a quiet courtyard of brick walkways or the street. A king-size bed or two double beds, TV, sink, easy chair, and chest of drawers furnish this space. Between the living room and the bedroom are the bathroom, small closet, and a kitchenette. It's worth requesting one of the eighth- or ninth-floor suites with views of Georgetown and beyond, as far as Washington National Cathedral (the hotel will note your request, but won't be able to guarantee you such a suite). For the roomiest quarters, ask for an "executive corner suite," the slightly larger, slightly more expensive suites situated in the corners of the hotel.Facilities: Restaurant (northern Italian); state-of-the-art fitness center with indoor pool, whirlpool, sauna; game room; concierge; business center (with free Internet access on 3 computers); room service (11am-11pm); coin-op washer/dryers; same-day laundry/dry cleaning; 8 rooms for those w/limited mobility, 2 with roll-in showers.

Hotel Monaco Washington, DC
Let's cut to the chase: This is where I'd stay if I were a visitor to D.C. The Monaco has been winning awards and great notice ever since it opened, summer of 2002. Museum-like in appearance, the Monaco occupies a four-story, all marble mid-19th-century building, half of which was designed by Robert Mills, the architect for the Washington Monument, the other half designed by Thomas Walter, one of the architects for the U.S. Capitol. The two halves connect seamlessly, enclosing an interior, landscaped courtyard. Jutting into the courtyard from the F Street side of the hotel is its marvelous restaurant, Poste, which got off to a rough start, but has finally established itself as a top spot for dining. The hotel takes up an entire block, between 7th and 8th streets, and E and F streets. Superlatives are in order: The hotel is truly magnificent.The spacious guest rooms, similarly, combine historic and hip. Their vaulted ceilings are high (12 ft.-18 ft.) and windows are long, hung with charcoal and white patterned drapes. Eclectic furnishings include neoclassic armoires and three-legged desks. A color scheme successfully marries creamy yellow walls with periwinkle blue lounge chairs, with orange damask pillows. Interior rooms overlook the courtyard and the restaurant; you'll see the charming arched passageway through which horse and carriage came a century ago. Exterior rooms view the MCI Center and the Smithsonian's National Portrait Gallery on the north side, and downtown sights on the south side. This is a great location: When you stay at the Monaco, you're not just downtown, you're part of the scene.Need more? The Hotel Monaco gives you a complimentary goldfish at check-in (if you so request); offers specially designed "Tall Rooms" with 18-foot-high ceilings, 96-inch-long beds, and raised showerheads, for tall guests. Go to the hotel's website or call direct to the hotel to obtain lowest available rates. With your own laptop, you have free high-speed Internet access in your guest room; otherwise, you pay $10 a day for Web TV access to the Internet.Pets allowed -- they get VIP treatment, with their own registration cards at check-in, maps of neighborhood fire hydrants and parks, gourmet puppy and kitty treats.

Omni Shoreham Hotel
This is Woodley Park's other really big hotel, although with 836 rooms, the Omni Shoreham is still 500 short of the behemoth Marriott Wardman Park. And it's all the more appealing for it, since it's not quite so overwhelming as the Marriott. Its design -- wide corridors, vaulted ceilings and archways, and arrangements of pretty sofas and armchairs in the lobby and public spaces -- endows the Shoreham with the air of a grand hotel. A massive $80 million renovation completed in 2000 installed a new air-conditioning system, restructured the pool, upgraded the already excellent fitness center health spa, and restored a traditional, elegant look to guest rooms and the lobby. The spacious rooms remain twice the size of your average hotel room and every guest room is equipped with free wireless high-speed Internet access, added in 2003. Most of the 52 suites are junior suites, with the sitting room and bedroom combined. The hotel sits on 11 acres overlooking Rock Creek Park; park-side rooms are a little smaller but offer spectacular views.With its 22 meeting rooms and 7 ballrooms (some of which open to terraces overlooking the park!), the hotel is popular as a meeting and convention venue. Leisure travelers, especially families, appreciate the Shoreham for its large outdoor swimming pool; its proximity to the National Zoo, excellent restaurants, and the Woodley Park-Zoo Metro station; and the immediate access to biking, hiking, and jogging paths through Rock Creek Park. Children receive a goodie bag at check-in that includes coloring books, puzzles, playing cards, postcards, and candy. You can walk to the more hip neighborhoods of Adams-Morgan and Dupont Circle from the hotel; the stroll to Dupont Circle, taking you over the bridge that spans Rock Creek Park, is especially nice (and safe at night, too).Built in 1930, the Shoreham has been the scene of inaugural balls for every president since FDR. Do you believe in ghosts? Ask about Room 870, the haunted suite (available for $3,000 a night).Facilities: Restaurant (continental; terrace overlooks Rock Creek Park); gourmet carryout; bar/lounge (serves light fare and has live music Thurs-Sat nights); fitness center and spa with heated outdoor pool, separate kids' pool, and whirlpool; children's gifts; concierge; travel/sightseeing desk; business center; shops; 24-hr. room service; massage; same-day laundry/dry cleaning; 41 rooms for those w/limited mobility, half with roll-in showers.
