PAX West Parking Question

Is it OK to park in the Convention Center for PAX West the entire weekend? I'm staying at the Westin but the convention center is cheaper for 24 hours of parking than the Westin. It's not clear if I can leave my car in the Convention Center parking from Friday morning until Sunday afternoon/evening though. Is that OK? I'm aware I'll have to get there very early on Friday to get a spot, which is certainly possible.

Edit: In case anyone else is wondering the same thing, I emailed the WSCC and they said it was fine to park overnight in the garage.
