We are a family of 4 visiting Maine for first time. We want to see Acadia, plus whale watch cruise (or something similar), and go on a lobster boat tour. Don't know best locations or boats for these excursions. We are on a tight budget. Is it best to rent a cottage (if so, where...off beaten tract), or would it be best to stay in 2 different locations in a hotel or B&B, closer to our chosen activities. We will be there week of August 17-24. Thanks for any advise!
