No. We used Reggie's - regtourbz.com. He was very good and we felt we got a lot more cave tubing for the money. There are several cave tubing tour operators in Belize. Reggie has been doing it for a long time.
About halfway through our float he pointed out where the ship's tour put into the river. I definitely felt like I got my money's worth.
