There's also a ride at Denver's Elitch Gardens (I live nearby) called Ghost Blasters as well. It's pretty similar. It's pretty decent! There's a sceance scene, and changing portraits (kind of) like the Mansion! And they have a waterfall effect thing like Davy Jones in Pirates of the Caribbean as well!

Here's a video (not mine): http://www.youtube.com/watch?v=_vv3xiELn-M
