OK, I'll take a chance at getting blasted to bits here, but I'm one of the few people who actually likes HISTA.
If nothing else, it's a nice cool (or warm) place to go for a while, it's not crowded at all, the line is short (or non-existent), and if you have a somewhat positive mindset, it can be an enjoyable show.
True enough, it's a bit outdated, but in its time it was cutting-edge technology. How many movie theaters have the air jets to simulate the mice running up your pantlegs?
There's a lot of nostalgia at DL, and HISTA sort of fits.
I agree, it really doesn't belong in TL, but where else would it fit in? Pooh doesn't belong where it is either, but where would it fit in?
I'm really not one to judge though, I can't see how anyone can actually enjoy a roller coaster. But a LOT of people do!
This is what makes DL so special; there's something for everyone. Very few amusement parks can make that claim.
