Great idea, not so great execution. We really liked the idea of indoor minigolf but in fact it wasn't very enjoyable. And expensive for what it was. Yes, great to be indoors on a hot day (it's in the mall basement). But:

• Black light + loud music means 2 of your 5 senses are a little impeded. Not great for seniors (2 in our group), or anyone hard of hearing. I found that element of the experience just kind of irritating: we had to yell to communicate, so it wasn't relaxing the way minigolf usually is. My school aged kids both complained the lighting gave them headaches.
• Understood that ADA requires breaks in the borders around the holes for accessibility, but this removes an essential element of minigolf. Key parts of the wall are unavailable to use as a bumper to hit your ball in. And be prepared for members of your group to act as backstops in those breaks in the wall, or for your errant balls to bang into others' field of play.
• Agree with others that course was generally monotonous, and yet where they did try to make it harder it was extremely hard. For 2 holes, the structures that you had to hit the ball thru were so badly maintained that you lost the ball in holes inside - unintended penalty.
• Also agree that timing for groups larger than about 4 was bad. Our group of 6 was constantly delaying those playing behind us. I think those playing on a weekday might have a better experience. It wasn't super crowded during our play, but it was a Sunday afternoon.
• Just FYI, it's a little hard to find. Best to park your car near Hughes Alley like you're entering the mall thru JC Penney, but enter GLO from the outside of the mall, to the left of Penneys, on the side closer to 91.
