Crystal has karoke, bingo, trivia, computer classes, wine tasting, dance lessons, yoga, bridge lessons, golf lessons, deck tennis, a crafts class that does needlepoint, painting and quilting, guest lectures, cooking demonstrations and a casino. I probably left out a few things, but be aware that the entertainment staff (dancers and singers in the shows) are the ones who staff the activities like bingo and trivia, and Crystal hires experts in computers, bridge, golf and all the other activities, so unless you're an expert in one of those fields or are a trained dancer/singer, you might be out of luck. Crystal's ships are very small and the staff that does those activities is quite small.. The Crystal Society hostess or the Travel Manager also host many of the activities on board. Crystal is a very different experience from any of the P&O ships.
