I realize that there is a good probability that no one can answer this question, but here goes anyway. On the southern caribbean cruise out of San Juan on the Golden Princess, one of the ports of call is Grenada. On the excursion list on the Princess site, there are 2 cruise/beach excursions(GND-S Sail and Beach Party @ $49 and GND-R Party Cruise and Beach Exp. @ $34). I'm unable to see any difference in the excursion to account for the price difference and I don't have the excursion list that's available on the ship to research it further, such as the time of day of the excursions, etc. Can anyone shed any light on the reason for the difference in price. If no one knows, I'll just have to wait until I board, but it was worth a shot.
