Yes, I was a frequent deluxe cash buyer at Disney before joining
DVC. If you think the GF is going to constantly be running "rent one villa, get three free" deals during Christmas, you just must have never booked a premium cash room, during a premium season, in a long, long time.
I think you guys have lost perspective on how much money exists in the world and how few lake view villas actually exist at the flagship resort in the worlds largest tourist destination. Disney is not going to have secret codes, blow out specials, etc. to rent premium villas at Christmas at the VGF. Frankly, most people will be shut out trying to pay these prices to get the few rooms available.
BTW, the grand villas will cost over $35k for that same 6 days and will be sold out as well.
GF at Christmas is not, and will never be, Jos A Bank. The fact that you think this is some sort of "fantasy rate" no one really pays except a spare few is just way off. It is the true market rate for these rooms. There is no "secret" discount everyone is getting to pay less.
There are many, many people in the world happy to pay it.
