mom, dad and 2 teens visiting in Jan and staying at the Mayan for 4 nights. Looking for suggestions on things to do. Not interested in eating or drinking. I am thinking of doing a 1/2 day tour with one of the recommended drivers listed. What else should we look at doing that is not included? An example might be the harbor tour to the Isla de la Roqueta etc. We like shopping(local) and beaches. It looks like from the Mayan we have to rely on taxis?
