We have done the America's cup twice and it was fun both times. Would definitely do it again. Also have done the cruise ship's catamaran sail/snorkel and it was a good time. The shopping on the Dutch side is fun, also....wonderful Delft shop and don't miss the chocolate place. Your ship should dock righ near there so only if you have an hour you can still hit a lot of nice stores. We also snorkeled at Pinel Island which was good, but there were a few ladies without suit tops. Have fun!
