We have booked hotel blocks at the following hotels. When you make a reservation, ask about the Williams-Ragan wedding or use the link below:
Embassy Suites by Hilton Seattle Bellevue

We are still working on getting a block at the Quality Inn Bellevue, but that is a lower-cost alternative right next to the Embassy Suites.
As for getting to the hotels from the airport, it'll be easiest to rent a car/get an uber/ask Ben and I or other family to pick you up.
The best airport to fly into is SeaTac. Our wedding venue is in Issaquah, which is east of Seattle. While there is public transit connecting SeaTac to Issaquah, it goes through Seattle, and will take 1.5-2 hrs. If you are staying in Seattle, it's easy to get to most areas in the city from SeaTac via transit.
Driving from SeaTac to Issaquah will only take 20-30 minutes. Ben and I will do our best to pick you up, but if not Uber or Lyft should be available.
There is a bus that connects Issaquah to Seattle. Within the city, the chief mode of public transit is buses, and there is 1 light rail line. The buses are safe and clean. They will get you where you need to go, though they may not be quick about it. You can get a rechargeable ORCA card at the airport or a local grocery store for a $3 fee, or pay with cash. Rides are about $3 (including transfers).
