Carnival catamaran and snorkel in Freeport

Anyone done this? Does it run on time? Opinions?

My main concern is that the website says it runs from 1 to 4 and I absolutely have to be back at the ship for an event by 430 related to a group I am taking the cruise with.

If you are booking the tour through the cruise line, you don't have to worry about timing.. they will hold the ship for you in the event you are late. If you are booking the tour on your own.. well, then you are on your own and the concern is very valid.

Cheers,
