Travel Note
SeaTac Airport is the airport you're going to be flying into/out of. Travel to the venue will require a car. We do not have a block booked at a hotel, feel free to use any of the below options (or others if you find a sweet deal).
Hotel
Get them Marriott points.
House Or Rental
Vrbo has a ton of options in the area for short term rentals for groups of many sizes, would recommend checking it out.
House Or Rental
Almost exactly the same as Vrbo, book early!
