If you must go, here are my tips: -Take an Uber or party bus (if in a large group). But everything you read in other reviews is 100% accurate: horrible parking (it's actually a huge safety issue), WAY overpriced drinks, HUGE lines for the bathrooms, way too many seats crammed between aisles. I haven't been back here in 2 years but decided to grin and bear it to see Pink.
Unless you leave before the concert is over you will wait 45 min - 1 hour to get out of the parking lot. There are 5 parking gates but everyone must leave through one 2 lane exit. For the life of me I can't understand how this place (and the Village of Tinley Park) can't figure out how to get people out of here at the end of a concert. The problem is that most decent concerts in the Chicago area seem to end up here.
Despite only living 20 minutes from HCA I avoid concerts here at all costs.
