Went to Slaughter House and Death Row for first time Nov 1. This was about half as big as Death Row, but still well done with mostly actors. Their electric chair scene room was more dynamic than Death Row's. They had a neat green faced character that seemed to jump from spot to spot magically in a room when the lights went off then on. I rate Death Row at 8.5 and Slaughter House at 7. You will have fun at either, especially, from what I observed, if you have a date that screams easily. I doubt that any of these places will be better than Death Row if for no other reason than you get a good solid hour of fun, more stuff rotating tunnels at Death Row Haunted Prison which is huge but Slaughter House was good and less gore.
Pros: Good actors, Electric chair good, No steps inside
Cons: Some sex on playingTV, Some 4' high openings, thirty minutes
