For MHP's on Tues, when the party starts at 6pm the enterance for the party goer's is 3PM. On Fridays the party start's at 7pm, with the enterance starting at 4pm. You will find for the 3 hrs leading up to the start of MHP, that the crowds will be really heavy. Once the party starts, only those who have a wristband for the party can stay. The rest of the people are informed that the park is closed and directed to leave the park via Main Street. For the first hour of the party, you can't go anywhere without showing your wristband to CM's to access different areas of the park where the party is being held. Hope that this helps you out.
