I was able to go the second week of HHN and had a great time. During that trip I was also able to do the escape room @hunnylvr talked about in previous posts. We did the asylum and it was SO much fun. I been to a bunch of escape rooms and this is by far my favorite. I think my husband got more scares here than he did at the parks. It was very innovative and well designed. The staff was also wonderful! I believe there is still a discount code available for hhn nightmares members. If anyone is interested their website is http://www.dare2escape.com/
They are not very far from the parks so we did ours during the day before we headed back for HHN.
Also we did escape, but just barely.
