Thanks everyone! We went and are back. Took bikes, no car. Used the bikes just once. Worth the effort for the East Bay Bike Path in RI. On great advice from NJ info center staff member, we stayed at Liberty Harbor RV park. A sort walk to the ferry, hook ups, and 24 hr "parking" in a secure site for $95!!! High for a CG but not for,basically, IN NYC. For Boston, we parked at Abington station ($4 all day) and took train in from there. Very easy-and we're newbies!! Unable to park anywhere in Salem. Even the train station parking was closed except to Mass. residents due to construction. We just decided to leave. All our other travels were easy in our 29 footer. New England was beautiful as expected. As PA doesn't charge entry fees for State Park we were shocked at the fees charged just to get in/park in other states. For Acadia NP we stayed at one of the 2 parks that is a stop on the Island Explorer Shuttle. Awesome way to get around and see the park!
