Loved it!! High points: ropes course, 360 bikes. There are some very clever exhibits here! So unique. The employees were all nice. It was well designed for crowd flow but I would personally not enjoy it if crowded. I hear it is a madhouse in the Summer, and this would definitely have changed our opinion of the place... But the same can be said of any MB attraction. We spent 3 hours on a cold February day and thoroughly enjoyed it. The only downsides: If you are a germophobe... Bring and use hand sanitizer / wipes liberally! There are SO many things to touch. Also, I have played much better laser tag elsewhere. The price was good so that made up for it.
