Ah Bicker, simply put, you are wrong.
We were NOT told about the changes to DDP when we booked a bounceback offer in September. The CM tried to sell us on the new Deluxe plan, and the wine plan, but did not tell us the changes to the regular plan. I also was not told about the changes when I booked something very recently. (though the CM did confirm that we had been to WDW last September.)
For another example, I recently called and asked about the quick service dining option at CR (as I know the food court is closed). The CM started to tell me about Chef Mickey's and the Concourse Steakhouse. Not the new place that hasn't opened, Chef Mickey's Character buffet and the Concourse Steakhouse. I said, "but those are TS, not QS." "Oh Yeah, I see that now, "she said. There was more. She was totally clueless.
So maybe this person (op) WAS telling the truth.
