I'll start this review by saying we did two rooms in one night (hostage and professor) we had a blast in the hostage room and had we stopped there this would be a 5 star review. We chose to do the most difficult room second and the reason for my frustration does not stem from the fact that we were unable to complete the room, but once our time was up and a staff member came into the room to show us what we were doing wrong he realized we in fact didn't miss a step or do anything wrong but the piece of equipment that we couldn't get past was broken! He turned to us and said "oh yeah, you were right... This is what it should have done" and after tinkering with it for a few minutes he got it to function correctly. I was prepared for the fact that this room may be too difficult for us to complete (2 adults and 2 kids) but I was really taken back that on top of an already amazing challenge we were beat before we started.
