Went to this maze (last weekend, oct 1) and it was a lot of fun. Inadvertently went on an autism charity day. There were loads of people. The nice thing about this maze is that it is structured to be challenging. They give you a small map of the first section and you go to the waypoint in each section to get the next section's map. Plus, hidden somewhere in the maze are stamp stations where you stamp your map. If you get 4 stamps you get a bag of popcorn, if you get 8 you get 2 bags. So there is a lot of motivation to explore the whole thing. And lots of collusion with others.
There were other little things too. Like a pony ride for kids. A slide and giant pit of corn (kind of like the ball pits in chuck e cheese). And a giant sling where you put in a pumpkin and try to get the pumpkin to land in the middle of a tire in the pond.
Took about 30 min to get there from madison's east side and it's a fun drive. Definitely recommend it.
