Got a few extra minutes to rant ... so ... understand that this is all tied to saving on labor. They want to know EXACTLY how many meals they will serve at every locale on every evening. (some moron please come in and remind us that Disney is a business and has responsibilities to increase shareholder value by ANY means they feel fit and blah, blah and BLAH!)
That means that, as others have mentioned, you can be paying $400-plus a night for a room (you likely have too much money if you are, but that's another subject), walk up to what amounts to the coffee shop of your hotel, like the Grand Flo Cafe, the Kona Cafe, Captain's Grille, Olivia's etc. and be told 'we're booked for the night' at 6 p.m. with a location that is 40% full. You should ALWAYS be able to get into a deluxe resort's coffee shop, even if you have to wait a bit.
They just flat out are so money-obsessed that they do not want to properly staff the locales.
In the real world, businesses like that would go out of business. That is an amazingly blatant F-U to guests. Yet, most of you will take it and WDW standards will slip further. Yes, your vacation really would be ruined if you dined at the Swan, Dolphin, Waldorf, Hilton ... or especially the Red Lobster LBV.
My advice, which you won't follow, is if you really don't like this (or anything) use social media against them. Don't simply here. Organize a group of 500 or even half that to all call George Kalogridis and/or others at the same time and keep calling. They will not like that. They will take notice.
