For $35 it was an excellent deal, and I had two vacationing married women for good company.
Once on the island you could do 2 activities. I chose snorkeling and horseback riding. The snorkeling was only adequate, but better than I had hoped for. I got to follow a stingray for a while, and played tag with some fuflar fish. (a Harry Potter fish if I have ever seen one)
For the horseback ride I was worried about the tiny little horses, but they pulled out a big beautiful arabian for me to ride. He was easy with the reign, and I was able to walk him around to everything I wanted to look at. When we got out to the beach I (after asking permission) got him up to a run for a good stretch. Unfortunately the other horses decided to come along, and I had to slow down to a walk so that the other riders didn't have heart attacks ;-(
