As others have said, there is no longer a hand stamp required. You will simply re-insert your ticket at the turnstyle while placing your fingers in the biometric finger scanning device. The system is all computerized now. The computer will recognize your ticket related to your finger size. It will identify that you were in that park earlier in the day and allow re-entry. If you want to go to another park later in the day, you will need the Park Hopper option. Again the computer keeps track of where you have been and when.
