You are correct about switchbacks. They have always been around, even in the earliest days. Switchbacks themselves are not the problem, in themselves, as far as I am concerned. Perhaps my comment was not well placed, because as is noted in the last quote, even switchbacks can be surrounded by great décor and theming.
My primary concern, most recently evidenced by the new high-rise Hilton-type hotels (Riviera, Coronado addition, and now the "nature-inspired" concrete jungle proposed next to Fort Wilderness), is that the management seems to be considerably less interested in the immersive nature of theming for which Walt Disney World became known. Remember they had the "blessing of size" and were also a place intended to improve upon Disneyland. They were an immersive resort that could literally take you away to wonderful, exotic, interesting places. And now they seem to be less interested in that. That is my concern, not so much switchbacks themselves.
So, forgive me if my comment was not so well-placed. It was meant to respond to what I interpreted as
@marni1971 's implication (perhaps incorrect) that the company was cutting back on when themes matter (and in my view much more so than they should). He had said that the plan was now "to pick and choose when to create an immersive entertaining environment." That was the part I was lamenting. With or without switchbacks.
