I believe you should only do one and it should be X-Plor. I promise you won't regret X-Plor. X-Plor has zip lines (best), you can also do a cenote while paddling on a canoe, and ATV's around the park. The entrance also covers all you can eat buffet as many times as you want to go. The other two are so so but if you're on a a budget do X-Plor, X-Caret in that order.
