Andi, we usually start by checking TripAdvisor when looking for a hotel in an unfamiliar city. Then when we find a couple that look like they might fit our needs, we ask for local advice on a choice after we narrow it down. Maybe if you provide a little background on what you need. Airport location? Port? Seattle Center? Central business district? Do you have any affinity programs? Need a handicap room? Shuttle service? Restaurants, clubs, tourist stuff nearby? University area? Do you want Hilton/Marriott quality, or is Quality Inn/ Motel 6/ Super 8 OK?
We took a cruise from Seattle in August and took a limo from/to Redmond for the 5 of us. Nearly $100 each way, all in, tip included, but it was a bargain. Parking at the pier is over $20 a day and with lax security. Door-to-door service exactly when and where we wanted it. I recommend this. The limo holds more people/luggage than a taxi and costs less.
