Our experience has varied from year to year; however, it is generally a good time to be there. You will find others enjoying Thanksgiving week - so it is not as solitary as a week in December. In non-covid years, most restaurants and shops were open.
We have found that early morning coffee on the sun deck facing the ocean is possible - especially with sweatshirts and long pants. Lunch is generally a better time to enjoy eating outdoors, strolling the beach, etc. with T-shirts and shorts on most days.
As owners, we long ago stopped offering our home for rent at Thanksgiving so we could enjoy it ourselves.
