My husband and I are flying from the west coast to Portland in mid-September 2006. We want to see as much as possible from Ogunquit to Acadia National Park. How long should be plan to be gone. We will be renting a car, but hope to take some boat trips, too. Also, where should we stay in Portland? We are hoping to stay at as many B & Bs as possible, but would be open to a small hotel/inn.
