My husband and I and our 2-year old daughter are planning a late August trip to Vermont -NH -Maine. Do we need to book hotels etc. ahead of time or are there plenty of choices (we can camp also) to choose from? We start from Manchester, NH and will visit friends in Bethel, VT. From there we plan to drive through the White Mountains to Acadia NP and then back to Manchester, NH. We have 10 days to do this loop and with a 2-year old, we'd like to keep our plans as flexible as possible. Any suggestions on the route we should take or places to stay (including camp grounds) would be greatly appreciated. Thank you!
