We really wanted to do the party boat and I tried booking it online but I guess we should have called first to confirm because we showed up at the dock and they told us it was cancelled! Oh well, they directed us to the
DePalm sunset sail and arranged a discount for us to go on that instead. Sailing around the island at sunset is a magical experience. We enjoyed the open bar and even though it wasn't a "party" cruise, we sure had fun on it. Enjoy!
