Im going to a wedding on Saturday night at the institute. Will I be able to park at the Institute garage and when does it close?

If your there for an event. It should be open for that event.

I just went there this past friday to the harry potter expo there. They do have parking right under the building for $20 dollars a day. I dont know what time they close but i was there parked since 8am to arround 5pm if not later. But i recommend it since it is hard to come by a parking spot in that area. And for $20 dollars a day its a deal i consider fair.
