Hotel very nice but small rooms. We booked a queen and were upgraded to a king. Bed very comfortable. Staff very friendly and accommodating. Hotel within walking distance to most attractions. Front door to hotel locked after 10pm due to outside area. Security at front door during the day. Lots of homeless people along 3rd ave but they kept to themselves.

This was our third time staying at this particular hotel in the last 10 years so we have a history to compare it to. It will be the last time we stay here. For the room price and the options that you have to DEPEND on the hotel staff to provide for you in a timely manner, it wasn't worth it. Nice property to look at though

  • Whether you print it out or use an electronic one, you'll need your boarding pass to get on to the plane. You'll also need some kind of government-issued photo identification. If you're flying internationally, make sure your passport is valid and you've checked visa requirements.
  • Make time fly by even quicker on your short hop by packing the right gear. Think tasty snacks, a water bottle and entertainment. If you want your trip to Index to pass peacefully, put some headphones or earplugs in your carry-on bag too.
  • Whatever the temperature is doing outside, plane cabins can get cold. Bring a light jacket on board to keep yourself warm and toasty.

  • Be flexible with your travel dates and wait for sales or exclusive offers on business or first-class airfares.
  • Budget airlines offer business-class seats at affordable prices. Ditch the full-service carriers and look into these cheaper options.

  • Meander along lively streets and alleys, relax in cozy cafés and explore notable attractions like Lake Serene Trailhead. There are tons of things to see and do in this appealing city.
  • Pick up the keys to one of our reliable car rentals and venture out to Stevens Pass Ski Area. Close to the downtown area but far enough away from the bright lights, this sight is a magnet for travelers and locals alike.
