I'm planning a 3-4 day trip to Portland and was thinking about driving over to the coast and spending a few nights there. Seaside has been recommended by some family, so maybe a night there or up in Astoria. Any recommendations about what to see or places to eat along rhe coast? I'd be interested in any museums worth seeing in Portland as well. This is mostly a getaway so it will be a relaxed schedule. Looking for any insights or recommendations.
