1) Don't get sunscreen all in your eyes while there. It is completely miserable for hours. However, if you do, on our way back to the hotel, our shuttle stopped at someplace with an ancient Mayan medicine man. He had something burning and put his fingers into the smoke and then touched my eyes. The pain went away almost instantly and all the redness of my eyes was right behind it. It was really kind of freaky.
2) We went to a place to swim and play with dolphins. My kids and wife loved it. I don't really like animals in general, but it was still fun. If you want me to figure out what place that was, I can look it up.
