Flight
Although it will be a bit of a drive, I recommend you fly into SEA-TAC airport and then rent a car. You can also fly into Bellingham, but that often gets more expensive and you will still need to rent a car.

House Or Rental
You can rent an AirBnB in La Conner, Anacortes, or really anywhere in the Skagit Valley. I'd recommend staying in La Conner AND a lot of the rentals are within walking distance.
Hotel
There will be a shuttle to and from the venue. Call and confirm details before you book!
