Hello! We are planning a roadtrip to Boston late August with our 5yr old and 8yr old boys. Have researched with recommended tourist attractions like Children's Museum, Double Deck hop-on-off, etc. Can anyone give anymore suggestions and also for day or short trips nearby Boston? Have heard a lot about Cape Cod beaches/ Martha's Vineyard..is it better to do a day trip or spend a couple of days at the beach in Cape Cod/ other? thanks!
