In my experience, Schoodic Point (the next "finger" east of Acadia) is a far better place for "nature" subjects, and more accessible than many scenic places in the park. Wonderful rocks and shoreline. I spent five days there and didn't wear the place out - 8x10 in the morning when I felt strong, 4x5 in the afternoon.
A nearby town (can't remember the name) has a great place for a clam roll lunch. Motels on the Acadia "finger" but before Bar Harbor will have lower rates - we were there just after Labor Day, and the rates had already dropped. We found the cafe in Bar Harbor that opens at 5:30 for breakfast - excellent and cheap. There was a place we went for a lobster every night overlooking the harbor in Bar Harbor that was excellent, and reasonably priced. Lobster, fries, salad, and Chardonnay. Drool.
Came back with over 80 8x10 negs and almost 200 4x5s...and a lot of wonderful memories. I also learned that 16 8x10 holders was at least one too few. Bought 8 more when I got back.
Heck, maybe I'll see you there!
