Well, I remember during the reign of Emperor Pressler they took the attraction off the "map" but left it open...I think in an effort to discourage visitors so they could tell Eisner they had to close it because it wasn't being visited via the turnstile #s. Heck even the entrance was unmarked (except for some safety tape). After 9/11 they had their excuse to close it.
Granted, it was stale, with some archaic technology....can't wait to see the new one.
