How many parking spots does the iowa events center have?

Too many to count. But the answer is 1300.

Their parking lot across from the HyVee Hall entrance is HUGE. I would day hundreds of spots between that lot and the surround parking lots.This is copied directly from their website: "Parking is available north of the Iowa Events Center with entrances off of the following streets: 3rd Street 5th Avenue Crocker Street The Iowa Events Center surface parking lots offer the closest and most convenient access to the facility, and easy access to I-235 and other major routes after the event. ADA Accessible parking is available at the Iowa Events Center by entering the lot south of Crocker Street, next to Community Choice Credit Union Convention Center."

I suggest you talk to the groundskeeper

Its humungous!
