Depends on how short sighted they are. Literally every expense they remove "increases profits". Why not only run 1 monorail, fire half the cleaning staff for the parks, permanently lower hours for all parks to just 8 hours per day, and so on.
Sure, but that's not what I said. I said if they can remove it without losing any revenue. Some of what you said would likely drive away customers. If it wouldn't, well... then you might see that happen. It's pretty unlikely that the Grand Floridian is going to struggle to sell rooms without the orchestra, for example, even though the orchestra made that resort much better.
Current Disney has been pretty clear that the overall guest experience isn't that important to them as long as people keep coming/paying.
