The MHP ticket will allow you to enter the park for 3 hrs prior to the party starting. Show either you e-tickets or tickets that you have received in the mail to the turnstiles, and they will give you: a wristband, a special ticket for the event, small goodie bag and a map of where the TOT stations. Once the party starts the CM's are out in force looking for wristbands, so that the people who have not paid for the event, are told that the park is closed and are directed to Main Street to exit the park. I personally loved the MHP event last year, and can't wait to go again. The best time to do the rides is when the parade is on, as they will have minimal lineups. Hope that this helps you out.
