How's the weather in Bar Harbor mid to late July? Does it rain a lot? We plan to drive to Bar Harbor for a weekend (from Albany, NY - approx 6-7 hours to drive?) and plan to spend most of the time at Acadia park. What can we in Bar Harbor if it's rain? We haven't made any hotel reservation yet. (The Quimby House Inn and some other recommended Inns have a cancelation fee.). Thanks in advance.
