We stood in line for about 45 minutes. The staff informed us that the inside tour would take about 15 minutes, and the "Haunted Forest" would take about 5 minutes.
The coolest part about this "house" was the makeshift elevator in the beginning. Very impressive.
It felt like it only took our group of 5 about 5-7 minutes. The chainsaw guy at the end was a nice finish.
The "Haunted Forest" had only a few scares in it. I was half-expecting another chainsaw guy at the end of the path, but there was nice.
