I'm sure we'll be up by noon on at least one of the days we're there, lol. Well, maybe not. ;-)
I've heard that the nightlife really doesn't get going until after midnight, so our general plan to deviate from is to be up by 2pm ..., shop/relax on the beach until late afternoon, catch dinner and the sunset somewhere, head back to the resort for a nap, hit the clubs around midnight until 3 or 4.
