Though TDO refuses to spend the cash for most of the overlays, which is cheap on their part, I have to admit that I breathe a sigh of relief whenever Haunted Mansion Holiday gets kicked out of the Mansion. To me, the story is nearly as contrived and intrusive as Frozen in Norway (I know some will disagree) and seems to come from a place of inherent cheapness on TDA's part as well.
Why give a popular IP that moves merchandise (an executive's wet dream) a dedicated attraction that could then be marketed during two major holiday seasons as the headlining attraction when you can mar one of the resort's best attractions for a third of the year for a fraction of the cost?
I know the last part of that question is the answer to it, but HMH has always stuck out to me as a reflection of TDA's classics be damned if there's money to be made attitude, even if there's a better solution to be had. So on one hand, I wish TDO were a bit more free with their wallets, but on the other, sometimes that serves as the only barrier between Star Wars in Disneyland, Guardians in the Tower, Nemo in the subs, and Nightmare Before Christmas in the Mansion.
