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

Peggy Notebaert Nature Museum
Built into the rise of an ancient sand dune -- once the shoreline of Lake Michigan -- Chicago's newest museum bills itself as "an environmental museum for the 21st century." While that might sound fairly dull, most of the exhibits here are very hands-on, making this a good stop for active kids. Shaded by huge cottonwoods and maples, the sand-colored exterior with its horizontal lines composed of interlocking trapezoids itself resembles a sand dune. Rooftop-level walkways give strollers a view of birds and other urban wildlife below. Paths wind through gardens planted with native Midwestern wildflowers and grasses, and trace the shore of the newly restored North Pond.Inside, large windows create a dialogue between the outdoor environment and the indoor exhibits designed to illuminate it. Don't miss the Butterfly Haven, a greenhouse habitat where about 25 Midwestern species of butterflies and moths carry on their complex life cycles (wander through as a riot of color flutters all around you). Another top exhibit is City Science, a 3,000-square-foot, two-story "house" with functional rooms where visitors can view the pipes and ducts that connect our homes with power sources miles away. Water Lab is a model river system demonstrating the uses and abuses that a waterway undergoes as it meanders from rural to urban environments. It's probably safe to say that the Children's Gallery is the only place in town where kids can clamber in and out of a model ground-squirrel town or explore a beaver lodge from the inside.The sunny Butterfly Cafe offers fresh, healthy meals cafeteria-style. In summer, get there early to enjoy coffee and a muffin -- and the lovely surroundings -- with joggers and other locals.Allow 1 hour.

Museum of Science and Industry
Even if you don't plan on spending the day in Hyde Park, you'll pass through the neighborhood on your way to one of Chicago's most popular tourist attractions. The massive Museum of Science and Industry is the granddaddy of interactive museums, with some 2,000 exhibits. You should plan on spending at least a couple of hours here, and a comprehensive visit can take all day, especially if you catch an Omnimax movie while you're here. Although it's quite a distance from the rest of Chicago's tourist attractions, it's easy enough to get here without a car; your best options are the no. 6 Jeffrey Express bus or the Metra Electric train from downtown (the no. 10 bus runs from downtown to the museum's front entrance during the summer).While the museum is constantly adding new exhibits to cover the latest scientific breakthroughs, you shouldn't miss certain tried-and-true exhibits that have been here for years and epitomize the museum for Chicagoans. The U-505, a German submarine that was captured in 1944 and brought to the museum 10 years later, brings home the claustrophobic reality of underwater naval life. The full-scale Coal Mine, which dates back to 1934, now incorporates modern mining techniques into the exhibit -- but the best part is the simulated trip down into a dark, mysterious mine. Get to these exhibits quickly after the museum opens because they attract amusement-park-length lines during the day.Kids who love planes, trains, and automobiles shouldn't miss All Aboard the Silver Streak, a refurbished Burlington Pioneer Zephyr train with on-board interactive exhibits; the massive model train exhibit that makes up The Great Train Story; or Take Flight, an aviation exhibit featuring a full-size 727 airplane that revs up its engines and replays the voice recordings from a San Francisco-Chicago flight periodically throughout the day. Computer addicts should be entranced by Networld, which offers a flashy immersion into the Internet (with plenty of interactive screens). More low-tech -- but fascinating -- is the giant walk-through model of the human heart. Well-designed educational exhibits include AIDS: The War Within (which was the first permanent museum exhibit on the immune system and HIV) and Reusable City, which teaches children ecological tips with implements that they might find in their own backyard. Older children with a creative streak will enjoy Enterprise, which lets visitors take on the role of CEO for a day as they immerse themselves in the goings-on of a virtual company.And, not to be sexist, but girls (myself included) love Colleen Moore's Fairy Castle, a lavishly decorated miniature palace filled with priceless treasures (yes, those are real diamonds and pearls in the chandeliers). The castle is hidden away on the lower level. Also tucked away in an inconspicuous spot -- along the Blue stairwell between the Main Floor and the Balcony -- are the Human Body Slices, actual slivers of human cadavers that are guaranteed to impress teenagers in search of something truly gross.A major newer addition to the museum is the Henry Crown Space Center, where the story of space exploration is documented in copious detail, highlighted by a simulated space-shuttle experience through sight and sound at the center's five-story Omnimax Theater. The theater offers double features on the weekends; call for show times.When you've worked up an appetite, you can visit one of the museum's five restaurants, including a Pizza Hut and an ice-cream parlor, and there are also two gift shops. Allow 3 hours.

Chicago Trolley Company
Chicago Trolley Company offers guided tours on a fleet of rubber-wheeled "San Francisco-style" trolleys that stop at a number of popular spots around the city, including Navy Pier, the Grant Park museums, the historic Water Tower, and the Sears Tower. You can stay on for the full 1 1/2-hour ride or get on and off at each stop. The trolleys operate year-round, but winter visitors won't need to wear a snowsuit; the vehicles are enclosed and heated during the chilliest months. The same company also operates the Chicago Double Decker Company, which has a fleet of London-style, red, two-story buses. The buses follow the same route as the trolleys; if you buy an all-day pass, you can hop from bus to trolley at any point.

Make your reservations for discount hotel rooms in the Chicago area, including:

Sofitel Chicago Water Tower
The latest addition to Chicago's already-crowded luxury hotel scene, the Sofitel aims to impress by drawing on the city's tradition of great architecture. French architect Jean-Paul Viguier created a building that's impossible to pass without taking a second look: a soaring, triangular white tower that sparkles in the sun. But the place doesn't take itself too seriously, as you'll see when you walk in the airy lobby and check out the luminescent floor tiles that change color in a never-ending light show. The overall feel of the hotel is European modern; you'll hear French accents from the front-desk staff, and foreign-language magazines are scattered on tables throughout the lobby. The bright, stylish Café des Architects has become a favorite business lunch spot for locals.The guest rooms feature contemporary decor with natural beechwood walls and chrome hardware. All the rooms enjoy good views of the city (but the privacy-conscious will want to stay on the upper floors, where they won't be on display to surrounding apartment buildings). The standard doubles are fairly compact -- but thanks to large picture windows, the spaces don't feel cramped. The luxurious marble bathrooms (with separate tub and shower stall) are quite spacious. The amenities are top-notch. Recognizing that business travelers are the bread and butter of Chicago hotel profits, ample support services exist for working visitors. But this doesn't mean that Sofitel doesn't welcome families; in fact, up to two children can stay in a room for no extra charge (they'll even roll in a portable bed for the kids).

Hampton Inn & Suites Chicago Downtown
While the Hampton Inn does attract some business travelers on a budget, it is mainly a family hotel. You can book a room, a two-room suite, or a studio; most don't have much in the way of views, but request one overlooking Illinois Street if you crave natural light. Rooms are residential and warm, with framed collages of vintage Chicago postcards on the walls. The apartment-style suites feature galley kitchens with fridges, microwaves, dishwashers, and cooking utensils. An American diner is located off the lobby, and a second-floor skywalk connects to Ruth's Chris Steak House next door. Guests with children will appreciate the indoor pool (the suites have VCRs, for when the little ones need to chill out after a busy day). Children under 18 stay free in parent's room, and there is a complimentary buffet breakfast each morning.

Le Méridien
Tucked into the Westfield North Bridge mall, Le Méridien is a fairly recent addition to the competitive high-end Chicago hotel market, and it seems that the general public has yet to discover it. Le Méridien touts its design philosophy as "European with a French accent," which, in this case, means marble floors, vaguely 18th-century-inspired furniture, and some whimsical artwork (a large painting of a Napoleonic figure with the head of a dog hangs in the lobby). A terrace offers outdoor seating, and a casual bistro is hidden away in the back of the lobby (depending on your perspective, it's either pleasantly secluded or isolated). Rooms are a bit small (especially the least expensive ones on the north side), but the amenities are top of the line: The safes come with chargers for cellphones and laptop computers, and the in-room phones are cordless. High rollers will want to book one of the suites overlooking Michigan Avenue; a few even come with private terraces, something few hotels in this city offer. Le Méridien can't compete with the Park Hyatt or the Peninsula in the glamour department, but its cozy style should appeal to travelers looking for some place a little more personal. It also makes a good base for anyone visiting during frigid winter weather; with a whole mall just a few steps away, you can get out without even putting on your coat.
