Making some changes from what was planned in order to save money is inevitable, and that’s fine.
Better to go ahead and spend the time and money now to make sure the end result is something that not only guests, but the park itself, is happy with.
Cancel or change something that hasn’t been announced yet.
It’s certainly true that Disney parks fans can get upset if something new is seen as being done on the cheap, but more importantly than that, whatever gets done now is going to stay that way for years.
