We stay at the BWV during early December and always take a stroll around Crescent Lake on arrival day. We stop in the lobbies of all the hotels to see the Christmas decorations - BC, YC, Dolphin, Swan, BW and we even walk back to the comon rooms of the BCV.
As mentioned, the Dolphin has a GIANT toy train filled with gifts that travels around a HUMONGOUS tree. Believe Santa occasionally makes a vist there as well. Love the life size tioy ssoldiers, too.
As also mentioned, the Swan has a wonderful ginderbread town display. Even now, I can smell the gingerbread.
The other hotels all have beautiful displays, too - well worth the short walk around the lake to see. Of course, our favorite is the BW, LOL., but no matter where on site you stay, you won't be disappointed,
Best wishes -
