First the pros: Well organized and run like the machine that it is. The tour guides somehow manage to corral people back onto the busses (during the land excursions) in a way that isn't bossy, and they never needed to harangue people to wrap things up. The event started and ended on time, and I felt fully informed and confident in each activity.
The cons: This. Is. A. Booze. Cruise. It is loud from start to finish. There isn't a moment to be with your own thoughts while looking at the island or gazing into the water. Music was blaring from 9am until 4pm, nonstop. If that's what you expected, then go for it! I was not expecting a dance party at 9am, and should have booked a private tour in retrospect. (How loud? One day, we were in a hotel room and thought we had a new neighbor move in who was playing their music loudly. Nope - it was a Sea Spray catamaran - on the water - easily a mile away.)
We're old. We look forward to keeping our hearing as long as possible. And if that's our only complaint (and it is!), then totally fine.
I am deeply impressed with how patient the crew was with all of the guests (including me, to be honest). Guests were continually asking the crew to take their pictures for them, even when the crew was obviously trying to work on boat rigging, etc.
Also a con - communication in advance of the cruise could be improved.
