Boobs Cruise is a must we have heard and it happens during the day so you don't miss the party at night .. I have heard that the resort doesn't do the trips to coco bongo anymore I know people have said that coco bongo is just packed to the rafters so they don't stay to long then they come back to the party at TTR do they have a website that says when certain things go on at the club ? We haven't been to cenotes but I think its just a day trip so you would be back in time for the party .. we did Chichén Itzá with the tour company it was a very very long day but we did get back in time for the party that night .
