Be careful how you hang stuff, if the stuff you use leaves a residue or by chance pulls any paint off when removed they can charge you. Personally, I dont mind if people decorate inside their room (not counting the windows) so THEY can enjoy it while they are in their room. But I personally, and again, this is me, dont like to have the theme of the resort 'broken' by stuff hanging on windows and doors. I know some people decorate them so the door is 'easier to find', but I still just think a lot of times it's more a 'We're here and we want to make sure everyone knows we're here'. I guess I'll admit if it was just one small wreath it wouldnt bug me much, but just think about others that have to look at it also. Trust me I'm not scrooge, I love houses that are totally decked out, but at WDW my mind seems to change.
