It's very warm; it's very cozy. Imagine a National Park lodge decorated for Christmas with a massive tree in the lobby, lights everywhere and you kinda get the picture. Actually, my words do not do the effect justice.
If, for counter example, a structure which looks antiseptic contains a Christmas tree, then it looks like an antiseptic structure with a lighted tree.
Wilderness Lodge and Christmas go together like hot chocolate and marsh mellows.
