MY husband and I did it a few years ago when we were cruising without the kids. We have done a lot of snorkeling and I thought it was just ok. We didn't see very much compared to other snorkeling trips, but if it is your first time snorkeling you might think it was kind of neat. We had been to CC before but even then I was a little bummed that it took up half of our day. If this will be your first time to CC, it will seriously cutt into your time to explore the rest of the island so make sure you are ok with that.
