Charlie is #1 in my book. You will not be disappointed. Charlie answered my emails from the states before we set out on our Norwegian Cruise. Charlie answered my emails while on the cruise and CHARLIE met us right on time at the cruise port in Belize. Can't miss him - His team wears the special superman T-shirt. Charlie loves what he does and loves to share what he has learned even more. He will truly educate you on the area, the nature and history of Belize caves. Cave tubing with Charlie was the HIGHLIGHT of my 20th Anniversary cruise. This guy knows his stuff and everybody knows Charlie!! Take my word for it - This is #1 cave tubing experience where you get the personal touch and you don't have to worry about being treated like your on a tour. Charlie's cave tubing is like meeting up with friends and enjoying the ride. He makes sure you are comfortable and well taken care of through out. He is so nice, he gave stranded cruise goers a ride back to the port - FREE! Charlie is a good guy and you wont regret tubing with him for a minute.
