After you choose your date, you will be asked to choose a group. Your group selection will determine who you line up with (think of them like boarding passes).  If the time slot you are looking for is sold out or doesn't have enough tickets available for your entire party, try another group. Each group has tickets for all time slots. If you and your friends end up with different times or groups, you may all enter the haunt together at the later time.

The Haunted Farm opens up at 6:15. You may come in to the park any time after this with a valid ticket for the night. Even with a late time slot, you may still come in to enjoy food & other entertainment before your scheduled time.
