Flight
Seatac Airport is typically the least expensive airport option if you are flying in. The Mukilteo Ferry terminal is about a 45 minute drive under the best, trafficless conditions. Once you depart the ferry in Clinton it is about 20 minutes further to Madrona Bluff House.
Flight
If you can get a flight into Paine Field in Everett, it is by far the most convenient. The ferry terminal is a mere 10 minutes away.

Travel Note
If any guest prefers not to take the ferry, Deception Pass at the top end of Whidbey Island is always a beautiful drive around option. If you are driving down from up north, this is your route.
