I have WDW stuff randomly scattered around my apartment. Of course, I spend a good part of every week at WDW, so I suppose that should not be much of a surprise. The only things that I associate with WDW that is kept organized on a daily basis are my work things: black socks, bandanas, flashlight, lighter, and earplugs.
I think the napkin issue is interesting. Just the other day in the MK locker room, a bunch of us were discussing if the guests ever really bring home their napkins.
