I was there a couple of months back... You should go for the experience.. its worth and special... its absolutely dark... pitch dark.. ur eyes get used after a while so you should be okay... Its fun too.. ur wife might like it... i though i might get scared of darkness but there are people around you talking loud and keeping you company though u cant see them.....

I would recommend a visit... You should take your wife for her bday.. my husband took me on mine and I was all excited!!!
