definately go for jolly pirates
their crew is very friendly, their prices cheap, and they are very entertaining. if you snorkel they take you to a german wreck and reefs, and they have the rope swing. also depending on what cruise, the rope swing
so if you are up for a more upbeat ship go for jp. when you get back let us know about your trip and who you went with the sailing. wish i was there. have fun and take pics and post.
