Anna, you can definitely travel to Seattle for each visit. The first visit takes about 7 hours with all the preliminary stuff, so that's an overnighter, but the remaining visits take only 2-3 hours so it would be possible, depending on where you are, to fly in, have the vaccine and fly out the same day. There are shuttle services from the airport to the University, and also if you need to stay over some of the hotels offer shuttle service to UW also.
Contact Patty Fintak with the Tumor Vaccine Group to help determine your eligibility for one of the trials, they have several going:

Also, here's a link to the Patient Family Housing Guide for UW:

Depending on your stage and status, there are several possible trials for you; the one I qualified for involved 6 vaccines, and Michele U was enrolled in one which involved only 3 vaccines. Definitely contact Patty and get the ball rolling if you feel you might qualify. Good luck!
