We are trying to come up with a Spring Break vacation from Portland. (Technically we are temp residents from AZ here) We have three kids ages 8, 5 and 2. The coast is out of the question because we don't want to deal with high school/college kids and the traffic. Seattle is the first thing that came to mind. Thought about Boise but now husband is saying he doesn't want to drive for more than 4 hours if need be. Any other suggestions?
