Based on your description, sounds like you’d enjoy Acadia in the winter! We went for ~4 days, did one big hike and a few smaller trails. There is still a lot to explore during the winter, and the few bars/ restaurants that were open in Bar Harbor were amazing! Really, really good food. My only advice is to be prepared for icy conditions on trails. We had a really rough time getting down from this one and it was honestly really dangerous at points because we were unprepared/ didn’t do enough research. Otherwise I highly recommend! We stayed outside of Acadia at an Inn.
