Can I purchase the Halloween Horror ticket without buying a day pass to the park? Or do I need both? When I buy on-line, it tells me that I need to put in my name, and that each pass is for the individual user, so when I come to the event, does that mean i need to make sure to bring an ID to show at the gate? I will be using the 'print at home options' so at what point do I need to show an ID if I am not buying at the gate??
