Flight
SeaTac will be your best bet for flights into the city. It is about 30 minutes via car (traffic pending) or 40 minutes via light rail to the city (cuts the traffic). Some hotels may have a shuttle service; it is worthwhile to check in with them.
Flight
A much smaller airport to the north, Paine Field is a delight in terms of lines and airport experience, but may be difficult if not impossible to find flights from different cities. Drive to the venue area is about 40 minutes without traffic, and there is not an easy public transit option.
Hotel
This is the closest hotel to the venue, and is right next to the shopping center that is University Village.
Hotel
Likely the cheapest hotel option very close to the venue, it is right next to a nice brunch place and directly across from a hospital, in case that becomes a need.
Hotel
A Marriott chain close to the venue.

Train
A great way to get around the city at minimal cost, the light rail has a stop about a mile and a half from the venue. It may be a stretch to walk, but it could greatly cut down on Uber or Lyft costs if you are not planning on driving. You could also find a hotel or rental near a different light rail stop near a different station for cheaper (Northgate Station will likely have cheaper options).
