Both SCUBA divers and snorkelers can do a trip together. We have done large combo groups before on our 40 foot party barge. Our divemaster takes the divers our snorkeling guide does the snorkelers. We party a little and do Shark Ray together. Those who don't want to get wet can sunbath on the deck. If we can help, let us know. We have also done weddings and receptions on our party barge.
