FYI, The Ultra Violet party at Negril Escape is A really loud, really late ultra all inclusive party, if your into a good loud late party its perfect, but its a fairly young crowd of mostly more upscale Jamaicans. I know of this first hand as I was staying there a few years back with the whole family, there was not much sleeping going on that night as the windows were rattling until 5 something am!
Canoe is always a good time as well as Seastar has there usual saturday night type party.
I am not sure what plans we have earlier as we arrive that afternoon, but am tentitively planning on a late night visit to Bourbon Beach.
