It would not have "taken over" the campgrounds. IIRC all campgrounds would have stayed in tact. A very Wild Lodge-esque type complex would have been put from just behind Trail's End all the way over to Fort Wild almost. A large parking lot where the current ranch still pretty much is back there with thousands of rooms. New massive pool. That is what I was told from a rather solid individual.
Yes, that's the old rumour that has been around for a while, but the discussion is about a new, similar rumour that was posted on here recently:
Disney campgrounds going away for a new "flagship" resort because a stuffed shirt is worried Four Seasons might outshine GF?
Something I heard, I don't know anything about this.
