we were just there this past December.
Here's what I can remember:
BWV - gingerbread house in the lobby, story time by the fireplace, Santa was there one day. Nice holiday decorations throughout the resort.
BCV - Gingerbread carousel in the lobby (of Beach Club). Again, decorations abound. Nice lights outside as well.
we visited Yacht Club - trains in the lobby
Grand Floridian - BIG gingerbread house in the lobby. Nice decorations all around.
We ran into some folks who were
DVC members and they told us that the decorations were much less spectacular than in years past, so what we thought was nice might not be the norm.
I'll post more when I get home and look at some pix of my trip.
