VGF is gorgeous, but GF itself is a major tourist attraction. We did the sweet spot
DVC early December week at VGF, and the insane crowds in the lobby 24/7 with the tree and shopping and wedding parties and crowds -- ugh. We're past the stroller phase, but my husband uses a
scooter, so kind of the same thing. It stressed me out trying to get a spot on the packed monorail.
Only having the birdcage elevator was a PITA, monorails were always packed, and the buses were the worst I have ever used anywhere on property.
This year there's no gingerbread house, but they're installing a pretty sizeable permanent bar in the lobby. From the pics I have seen, IDK where folks are going to go if/when a tree/gingerbread house comes back with those insane crowds.
Don't get me wrong, VGF IS gorgeous. The rooms are lovely. The views of Electrical Pageant off our balcony was magical. You just want to go when it's MOBBED. At the very least I'd shoot for 150x2=300 at VGF, because needing peak weeks for the kids' school schedule is rough. We only do peak school weeks and a 1B, too, and 300 has done well for us. It's nice to have some wiggle room so you're not sweating a reservation.
If you would like/can handle the walking path to/from MK in December, I think that's the way to go.
Dining options are great, pools are very nice, and good shopping. It's really just the melee in the lobby/transportation that made me batty, but that may be an "us" thing. After several trips, peace back "home" at the resort trumps some location factors. I don't think VGF is ever a bad choice to buy -- definitely will hold resale value -- just manage expectations if you're going anywhere near November 1-NYD for getting around the hubbub.
