IF they can take the time to make and send out those stupid Deevey emails - then they could do this. I am willing to bet they could use the money they spend producing those stupid videos and keep paying for valet.
You may be right. But as others pointed out, that's a marketing expense and the two don't really have a direct impact on one-another. It's kinda like saying that Disney should stop running commercials and buying billboard space in Florida and instead put that money toward a new attraction. Not gonna happen.
Disney doesn't usually crow about changes which negatively impact guests. They don't issue press releases for ticket price increases or dining plan changes. Instead we have to rely on sites like the DIS or Allears to get that sort of info.
One could make the argument that we are "members" and deserve greater communications. I don't necessarily disagree, but I think in Disney's eyes it's a minor distinction. They placed a note on the member website and that's more than Disney usually does to communicate reductions in service. I believe I read somewhere here that Disney sent memos to current resort guests when the change occurred.
Disney has the resources to go further than that, but I don't think it would be consistent with their SOP over the last decade or so.
Maybe I have low expectations but I think the most they could have (would have) done was to put a note on DVCMember a few days earlier. Obviously they didn't but even then I don't know if DVC is to blame, higher-ups at Disney or if it's simply the result of drawn-out negotiations which left other divisions unable to respond in a more appropriate manner.
