I agree with LisaK. I stayed at an all-inclusive in Cozumel in 2002, and it didn't matter what I ordered to drink, Pina Colada, Margarita, etc...all the drinks with the exception of Cervesa, tasted like rum punch (watered down at that). The hotel that I stayed at offered non-motorized water sports for the guests; however, any excursions cost as much as the cruise line charges. If you want to go off property, it is just like LisaK said, you have to pay for it, whether it be only a taxi fare or taxi fare and ferry fare, depending where you want to. Bottom line...it can be quite expensive.
