I have an Aunt with a room like that(though I haven't seen her in years not sure if she still has all of it) only it's Goofy instead of Mickey.
I kinda admire people with enough collection passion like that to literally fill a room with it. I have realized though that there is more to life than collecting things. I have a pretty decent Dvd collection though I show off along with some Anime stuff(now I've starting going after blu-ray). I call it my geek cabinet.
I saw this woman on a TLC or similar channel show-- My Strange Obsession.
She has the largest MM collection in the world and she moved from Europe to Florida to be closer to Disney!
Wow, her whole house is Mickey! I could easily see myself slipping in to that if I were "allowed" to. Although for me, I'd do my house in Disney history. I'd like to get some old Disneyland attraction posters and some photos of the early days of Disneyland.
See my problem would be how to choose just one???? When someone asks me what my favorite Disney movie is, I really can't answer because I LOVE THEM ALL!!!!! I don't think I could choose just one Disney character!
