My first choice would be the little apartment in Cinderlla's Castle. Hands down.
However, assuming that is not an option then I would want to stay at A of A. I will explain my reasoning but it is kind of crazy so if you scare easily you have been warned.
When I go on vacation I like my hotel to match the theme of the location. I don't know why exactly, the contrast just throws me off somehow.
GF- If I was going to Mackinac Island or Martha's Vineyard or something like that I would be all about it but not at DW.
WL- While this is quite possibly my favorite resort I have trouble reconciling the national park theme. If I was going to Yellowstone or Yosemite then sure. But not at DW.
Poly- Meh. If I was in Fiji.
BWI- If I was in Jersey.
CR- If I was in the 70's.
AKL- I do have a small desire to stay there but I would never be able to justify the expense of a savannah view room to myself.
SSR- If I was in up state New York.
YC and BC CL- Just never had the desire.
CSR- This one actually speaks to me. Someday I may try this one out.
Basically if it doesn't look like Mickey threw up in my room then I don't really feel like I'm at Disney World.
I may be getting a touch of OCD in my old age.
