WDI tried to bring the Nightmare overlay to Orlando years ago but TDO keeps saying the characters will not be as well received because most visitors to WDW are foreign or don't know the characters. Fact is Jack Skellington is very well known and has been a marketing and merchandise phenomenon for years.
My point is Disney management has shot themselves in the foot for far to long and it's time capitalize on it. These characters should have be in the MK during Halloween operations for years and yet they half ass it again by shipping them to DTD for their first appearance. If people are willing to wait 3 hours at DTD nearly 20 years after the film was released how could these characters impact ticket sales if you did a Holiday overlay around them at the worlds most visited themepark? Merchandise sales anyone?
California and Japan have shown these overlays and character meet and greets to be an overwhelming success and go as far as adding new features to the overlay each year. There seems to be members at TDO who have their head so far up their asses or IMO are not willing to admit their wrong that they would rather stick to their guns and continue to say it won't work here, when the rest of the Disney parks scratch their heads in bewilderment.
To sum up that rant into one sentence,
TDO has dropped the ball on this from the beginning...
