We chose this trip mostly for the itinerary, but also because we were following it with a second trip, with the rest of the family, on the Jewel of the Seas, which was just returning to San Juan.
Our week on the Adventure was, to put it simply, smooth sailing. From boarding, to our stateroom attendant, to restaurant waitstaff, to the front desk personnel, it was a no-complaint trip. I rarely put Wows on survey forms, but everyone with whom we had contact on that sailing rated at least one.
The entertainment was generally good. I didn't enjoy one comedian, but the other headliners and the on-board singers and dancers were very good. The casino didn't take too much, and did offer longer low-limit hours than many we've seen. We tend to stay with our main dining room for dinner (and our waitstaff was fabulous!), so I really can't comment on the specialty restaurants.
