Bar Harbor and Acadia? Always beautiful.
Road to Bar Harbor? Under construction and a nightmare. Down to one lane into town with a detour to get out. It's supposed to be done by tourist season but from what I saw it would be a small miracle.
If you saw my post about the Hampton they're really nice about letting non-guests charge overnight but you're rolling the dice to get one of the close spots that the extension stretches to. If you charge up in Brewer, you really ought to have enough to get to the park, do some driving and get back to Brewer.
Had lots of fun in NH and VT as well if you're headed in that direction.
Detailed recommendations if you want to PM me.
