I doubt that
DVC folks selling their VGF contracts will move the mouse’s accounting needle, however, cash guests choosing to not book the GF might, as pointed out by a PP Disney needs to sell a lot of gingerbread to make up for unbooked $1000+ a night rooms.
I remember when the CA entrance was for GC only in the past - it was lovely, but when I stayed at the Grand Californian 2+ years ago, (& paid just south of $1000 a night for the privilege of staying there) I swore I would not return because the lobby was such a madhouse, especially the GC entry into CA, but also the security check points for DTD & DL which snaked through the hotel & it’s grounds, if they’ve addressed those issues, then perhaps I’ll be back.
If GF cash guests respond on their exit surveys as I did on my GC exit survey, perhaps Disney will implement some crowd control measures like a dedicated LL type entry for hotel guest access to the monorail & boats during high demand times, then lookyloos can decide whether they want to queue in the equivalent of a 7DMT standby line to wander around the GF lobby & buy a gingerbread shingle & hotel guests can have reasonable access to MK & Epcot.
I own at the VGF & typically stay there during the holidays & can remember waiting in one ridiculously long line in the main lobby for the monorail which reminded me of what the Poly monorail lines were like right after the luau dinner show let out. The MK park close monorail madhouse I avoid, opting to boat or, now that they have completed the path, walk. I am concerned about transportation for my visit in a couple of weeks, but more so because of the Poly tower & all of those additional folks using the monorails, boats & especially the buses because they pick up at the Poly first.
