Maze of Madness at 2001's FearFest was initially to be known as "The Morgue", prior to sensitivity concerns.
If you're looking at more examples of Halloween events changing attractions/displays over public response, I typed-up a lot of them a year ago:

Edit - And from this year, Universal Studios Hollywood removed a "darnation Army" sign from one of its attractions, supposedly after complaints.
"sensitivity concerns" I.E. Political correctness.
I wonder why they're making such a big deal about it now? It's been like 2 or so years we've had it as DDD.
