Oasis Near the Airport
If you just want a place to flop, go to one of the budget chains next to the airport. For a more luxe, "Northwesty" local experience, go to Cedarbrook. The free shuttle runs you the five minutes from Sea-Tac to this beautifully landscaped, tranquil hotel. No airplane noise at all in the hotel or the rooms. This is a beautifully-crafted hotel with all the amenities: free wi-fi, free continental breakfast (with tons of smoked salmon and artisan cheeses, eggs etc.), nice restaurant and bar, comfy bedding, big and well-equipped workout center.
The rate was reasonable for such an upscale property. We paid $149. Our room was smallish but had a Keurig coffeemaker, large flat-screen, ample work area and storage, nice bathroom, good task lighting and bed. A nice touch is the "living rooms" scattered throughout the guest wings. Big seating area with large flat-screen and complimentary snacks including fruit, ncandy, chips, bottled water, Haagen-Daz ice cream. You'll feel as if you had a mini-vacation in the mountains at this beautiful property.
