My husband and I want to take a trip to Maine this summer. He wants to see whales; I want to see lighthouses. We'd like to stay in the southern part of Maine on the beach. It's just the two of us, no kids, so availability of kid activities is not important. What beaches are clean, and not horribly crowded? Also, if you have a suggestion as to where to stay in your favorite beach town, that would be great too.
Thanks for your help.
