The first thing we did when we checked in was grab the camera and our swimsuits. Our camera went a little funk on us and decided to get moisture in-between the lens, so we put it up and used the iPhone for most of our excursions.
On this particular day we went to a park called XCaret. I'm not sure how to explain it. It isn't like a theme park where there are rides and such, but it isn't a national park either.. They are preserving the land? Ha, I don't know exactly. There are Mayan ruins inside of it, cenotes ,and underground rivers. There's an inlet from the ocean and you can snorkel. They have TONS of stuff to do- you need at least two days to TRY and get it all done.
