correct me if I am wrong, but is the grand Mayan in the Marina area? When we went there there was a string of shops, restaurants,etc right near the whole complex. You might want to check that out, hopefully someone can help you specifically.
There is a disco at the Mayan Palace that really doesnt happen until 11:00 pm. They have great drinks & drink deals & will pretty much play anything you want to hear. Nothing like in PV but still fun if you want to stay close, (its next door)We still had alot of fun there. Not much out there except beatiful beaches & nice resorts.
I have heard good things about the Club Cesar disco right next to the Marival. I am not sure if outsiders can get into it or not.
