My husband and I are flying into SEATAC the middle of July and renting a car to visit Mt Rainer,
ONP and San Juan Islands. We were going to spend the final 2 nights with friends on Whidbey Is. But plans change and we're not. I still want to ferry from San Juan to Whidbey to see Deception Pass. But then I'm thinking of taking Hwy 20 to the mainland. So the question is: What is there of interest to see/do between Burlington and Seattle? And what town would be best to stay in?
