It is great ONLY if you get to the ticket booth within precisely 90 minutes. If you don't they charge ridiculously high rates for parking: $2 for each 20 minutes. I planned on staying for a bit longer than the free 90 minutes and knew I had to pay $2 for the extra 20 minutes. No huge deal. However, I went to the monthly parking exit by mistake. I had to back out of that and go to the correct booth. That costed me an extra couple of minutes. 22 minutes of parking was $4...a bit too much in my opinion. I told the attendant but she didn't care. I was parked for an extra 22 minutes but charged as if I was there for 40 minutes. It is worth noting that they put the monthly parking exit in a more convenient place. Drivers without monthly passes have to go down further to get to the paid parking exit...which leaves more possibility to get charged for an extra 20 minutes. Uptown needs more affordable parking options.
