Well considering that I've gone down to Negril the friday after thanksgiving the last 9 years (including the last 2 years during covid), I can report that it always seemed to be the time when Negril picks up from the slow season. Even this last Thanksgiving we went to restaurants and saw some afternoon bands. I believe that only the curfew at the time of our trip stopped places from playing evening bands. It's always been my favorite time of year to go because most places are open with decent crowds, yet not too busy or packed like some months in the busy season.
