How much snorkeling did you actually do and where did you snorkel?
Was it money well spent?
We have considered doing a private tour = but I can concerned that if the ship is late, we will miss the tour. For example - the ship "docks" at 7am, and the pickup for one company is at 8:15. Ships have been known to arrive late, and if we book with a Carnival excursion - we won't miss anything even if we are late.
Any suggestions - either to doing one of Carnival's tours listed above or taking a chance and booking a private tour?
