The World That Never Was. Simply because it would be so out of place Imagine all the chairs in Where Nothing Gathers being decorated, and all Org 13 members wearing Christmas Hats

Agrabah or Beasts Castle

I think Twilight Town or Hollow Bastion would be interesting to see with Christmas decorations haha. 

I was torn between Twilight Town and 100 Acre Wood... I chosee the latter.

I love Pooh.

Really all of them, though it would be most awesome to see them in hub world locations like Hollow Bastion/Radiant Garden and Twilight Town. Though I'd also love to see how they would look in a place like Space Paranoids, electronic cyber Xmas Trees and whatnot. I don't think they would fit in Olympus Coliseum tho, cause uh, ancient Greece wasn't exactly a big fan of Christianity, so I doubt Zeus would appreciate all of that decor all over the place. X)"

As funny as it would be to see decorations in Port Royal or Xemnas in the World That Never Was with a santa hat, I pick Hundred Acre Wood because I've saw some of the Christmas episodes of Winnie The Pooh and the environment would be stunning to see in KH, with the snow, Pooh snowman, characters with little knitted scarves...I've made my point.

Christmas Town

 

In all seriousness, Pride Rock. That would look funny

 

Peace!

Twilight town, and Beast's Castle.

Although they did show that in the sequel...still, it'd be nice to see the KH version. Maybe even Christmas themed Heartless. 

Twilight Town all "christmased" up would make me so happy ^^

Beast's Castle would be even more beautiful with Christmas decorations.

Only problem in Atlantica is they can't use Christmas lights lol

 

Twilight Town

Twilight town. No question. I absolutely love Twilight Town. I would love to live there.

Christmas Town

 

I would choose Traverse Town because it's already quite dark with lots of bright lights; all it lacks are the decorations. But seeing as this topic is mainly about KH2 worlds I would have to choose the second best option for a Christmas make-over: Twilight Town. I believe Twilight Town would look stunning at night and with the addition of Christmas decorations the town would become absolutely magical.

Hard to decide between Hallow Bastion and Twilight Town
