Our family(we're from England, with two sons of 15,17) will be touring in a hired 32 ft rv in August for two weeks in New England. I've booked already two nights at Bar Harbor, but am unsure if I should reserve sites for most of the route (we're travelling clock wise up from New York (where we pick up the rv) towards Franconia, east through New Hampshire to the coast, then down the Maine coast towards Boston. I've no idea if we should just book for weekend dates, or will our choice be very limited re. free spaces at campsites in August if we don't pre-book? Grateful for any advice....
