If you have time to do the real thing instead of the theme park equivalent of it, all the better, IMO. My friends floated down a river in the Xcaret theme park with other tourists. We floated through the mangroves, down a Maya dug canal, past Maya buildings, in the Sian Ka'an biosphere, with our Maya guide commenting on the flora, fauna, and history as he floated alongside.We snorkled in a cenote to see the fish, with only the Maya caretaker and two local picnicking Maya families as company. Both couples seem to have had a good time according to their own taste and time.
