Here is an IDEA, When DW and I went to WDW, we FEDEX GROUND shipped out luggage ahead.
You could go and find a small artifical tree, pack it in a box witha few decorations (or buy them there) and FEDEX it to yourself at the resort!
It worked great for us, and when we were ready to leave, we FEDEX it back.
As an example of cost, we shipped a 60 pound hard sided suitcase from San Diego to the Poly resort for about $43.00! it was about the same going back. You can open an account for free with Fedex. (I know I sound like a salesman, but I'm not) You just have to remember that it will take a few days!
