We did it Sunday and thought it was great. My son (age 260 felt a little claustrophobic in the helmet but not enough to get out early. They give you an underwater camera to use while you are down there plus they use it to take group photos of your group. The photo CD was "only" $30 and I thought it was a bargain. You can take as many photos as you want - we had over 100 on our camera! The guides were great fun too.
