I would suggest to take an uber/lyft for the easiest in and out of the center. Otherwise, try your luck in the surrounding garages, but be prepared to pay a premium!
Best advice I can give you is to look for any parking lot. There is one right there but its usually crowded. They're all pricey.
Under there is parking
There are tons of signs. Can't miss it at all. Massive structures literally right next to the center.
