Things to do in Niagara Falls?

I took the wife into the haunted house (I think Frankenstein one) on Canadian side Clifton hill.
The worker at the desk asked me what stage of scary do you want ?
I pointed to the to the crazy one with live actors.. he looked at me and said are you sure?
That's when I knew it was going to be nuts..
We made it through the whole thing without exiting a "chicken door" .
It was also on our Anniversary..
Trust me she will never forget it. Lol
