Love your question. I am ALWAYS looking for Disney decorations for decorating our site.
I suggest: Kmart, Walgreens,
Walmart,
Disney Store, JCPenney, Sears, Lowes and more....
I try to snatch items up after the holidays-all (Halloween, Christmas, 4th of July, Easter).
My favorite item *CHRISTMAS* (which I can't find the picture to refer) was a small christmas tree, tree skirt was a red/white checker plastic tablecloth, red sewer hose was garland around the tree, The kids black mickey head shaped plates served as ornaments on the tree, santa hat with mickey ears-tree topper....
I grabbed a few years back in the meadows trading post was a mickey flag, and a mickey hand plastic plate (we place against the wooden campsite number).
