There are 18 in our group and 3 other groups from the boards all on 8/2 are going with Reggie - we have not read one bad word about him - in fact, everyone raves. He has never missed a ship in the 5 years he has been in business and has his own tender if a problem arises and it is needed. Reggie is also only $65 compared to Carnivals $85 and he goes into 3 caves not 2 and will still get you back before the cruise excursion.
I know people are relucant to book their own - but with over 30 of us going with Reggie on 8/2 - there is security in numbers
