We did the cave tubing with reggie last month. It was great. Not to worry about getting back on time they have been doing this for a long time and know what they are doing. If your husband can't swim I think it would be best just to wear the life vest and not have to worry. Reggies tours are far cheaper than the cruise line offers. Our cruise charged $96 and he charged $60 plus it was another $5 for lunch. The cruise lines trip went to one less cave than we did, we had 8 people in our group and they had at least 40. Also feel free to email Reggied and I'm sure he would be happy to answer any questions you might have.
