Great minds think alike! I have a roll of really nice, tapestry-type ribbon that I got at an after-Christmas clearance many years ago that I've never found a use for. But it seems to fit well with the type of decorating I have in mind so I am trying to figure out how to use it. I was thinking of wrapping a straw wreath or wire wreath frame with burlap ribbon, then using the tapestry ribbon for a bow on it, but that might be a bit much to pack. So I'm still noodling that.
While we open under-the-tree-gifts before we leave, Santa Mom does fill DDs stocking for Christmas Day, so that will definitely be coming with us and will become part of the decor. I ordered a special wood hook that will be easy to pack, but allow me to hang the stocking without damaging hotel property:

My SIL uses these types of hooks, and they are great at holding pretty heavy stockings. It's all about using the weight to balance itself!
I'll have to look at window clings. I got some nice snowflake ones a few years back that I used on a mirror in the living room - they looked really nice, not childlike. Good idea!
We are staying at a Hyatt Place, so the room is a bit more homey and has some surfaces that give me a bit more flexibility in decorating than a normal hotel room. I ordered a custom banner last night on etsy that says "Be Merry" in distressed lettering on individual blocks that I will string somewhere, probably on the bookshelf/TV area they have. Spent more than I probably should have on it, but I liked it and the seller worked with me on customizing it to make it even better
