Anyone have any comments on the nightlife at the actual resorts (specifically Moon Palace, El Dorado, Riu Palace Mexico and Dreams Cancun)? I've heard that some of them are a little more quiet than others. I don't want to have to leave the resort and go into town unless we have to, since all our drinks/meals are already paid for, but I know that a lot of our guests will want to drink and dance together on the other nights they are there besides the night of the wedding reception. Do most of these resorts have at least one bar (other than the pool bars) that will be open at night where everyone can hang out together?
