Also, some memories:
I personally only saw a relatively small number of people go through it compared to those that must have, but hearing the comments on the exit bridge was very rewarding. Seems we got the frustration level just about right and people liked that they could get out when they wanted, just not find the exit easily. A few young kids said it was the coolest thing they'd seen out there - you don't get better than that!
And I wish I been there personally for it, but one of our nightwatch crew apparently stood on the centre bridge at 3am with a packed maze and yelled at the top of his voice "In 10 seconds we will be shutting all the emergency exits and unleashing the minotaur - good luck". Apparently one guy nearly fainted and was heard freaking out with something like "OMG! Nobody warned me about that - help me!"
