I believe you get your hand stamped as they do in the parks if you have a one day ticket......as for Shark Reef I didn't go (scares the .... out of me swimming with any type of fish), but my kids did go (ages 13 and 11 then). They can't wait to go back, suggest early or first thing because if you wait any longer the line is really long and they hurry you along when you are swimming. I was told that the water is VERY cold. Great pictures come out but we used a disposable and don't have them online to post.
