Not only don't you have to get your hand stamped, you can't get your hand stamped. The CMs don't even have the stamps and ink pads. It used to be one of my traditions to get my hand stamped the last time I left a park before I went home. That was my way of saying to myself, "I'll be back!" Besides, what if I got to the airport and my flight was cancelled? You never know-I might need that! I was so sad to learn that I could no longer get stamped, even if I wanted to.
