- I booked my spot with Park Whiz for the U2 concert on July 1. I thought the rate was fair for an event like this and I liked how spacious the individual spots were. No trouble getting in or out of the gate. However, my reason for the 2 star review is the fact that I walked right into the plate glass stairwell entrance on level 4A. Don't laugh. I was not under the influence of drugs or alcohol. I have been trying to figure out over and over again how I could have mistaken that floor-to-ceiling glass "wall" next to the door for an open thoroughfare, but I can't. It all just happened so fast. Luckily, I do not have a concussion but I have a bad nasal contusion and my eyeglasses are messed up. Please consider putting some kind of marking on that glass. Thanks.
