YAY for WL and the tree!
We are going to Universal for Christmas (shhhh - the 16yo has - for now - aged out of WDW) But I couldn't go all the way to Florida and not make it to WL, so we have dinner booked at Whispering Canyon for Christmas Eve. So I will be able to shop and explore WL - my WDW home.
I remember, when we stayed there, meeting Santa with the kids by the tree on Christmas Eve, so I am hoping this might be possible too, although I am not telling them!
