I just posted this story on another Mummy thread, but it fits here too!
When we were there last week, we overheard a son in his 30's telling his dad who was in his 60's about the ride. Obviously it had been a while since he rode it OR his memory was really bad, because this was the description he gave...."It's just like Pirates, but without the water."

After the ride the we heard the father saying, "Wow, that is NOT what I expected."
So I would compare it most to Space Mountain (but WAY cooler!!). The coaster part is all inside, dark, no big drops, nothing upside down. But I would never compare it to Pirates!
