Zombie Set Times / Parking Lot

What are the set times for the show on Sunday?

Also, doesn't pre-paying for parking guarantee a space in the lot? The last time I prepaid for parking, the lot was "full" when I arrived and I was told I had to park on the street. No one, of course, offered me a refund. So if a space isn't guaranteed, what time do I need to get there to make sure I didn't waste $15 on advance parking.

Thanks.
If you purchased a ticket in advance then should have been a space held for you. If you pay in advance for parking your spot is guaranteed and if you are told the lot is full ask to speak to the e-park rep or the 9:30 manager on duty.
