We are staying at the Crowne Plaza Union Station, downtown.  We are planning on parking in the adjacent Pan Am Plaza parking ramp.  Does anyone know if this parking ramp is safe to park for 5 days?

I have parked there multiple times during Gencon and never had a problem. Twice for the entirety of the convention and other times just daily when staying at an outlaying hotel. I visit the car every day to drop stuff off or pick up bottled water I kept in the trunk and never felt in danger for myself of the car.
