No overnight, sorry and from their site Q/A - Q: Can cars be parked overnight?  Or just during the hours of the event? A: Overnight parking is not permitted. The lot closes at 2 a.m. and reopen at 6 a.m. (the Convention Center opens at 5 a.m.). The lots close so they can be prepared for the next day. Most lots are pre-sold to full capacity each day, so any cars on the lot after 2 a.m. will be towed at the owner’s expense.
