The cave tubing is a blast. I would make sure you bring your own scuba gear or trust who you are renting from to do the blue hole. we had an experience last time with renting for the blue hole dive and the regulator had a malfunction at 120feet and had to do an emergeny acent to the top. so now we still dive there and are going back but we take our own scuba gear. But the cave tubing is a must and the dive site are beautiful. have fun and congrats.
