I would without a doubt pick Magic Kingdom. I'd just love eating breakfast at the bakery on Main Street every morning and see all of the smiling faces eager for a day beyond the castle.
Definately Epcot. I think I would like to redo the whole Odyssey Restaurant area to be my own private flat. The word showcase out back and future world out front. Nothing beats that to me!!!
Epcot. When I was a kid, I used to pick out which facade in Biergarten and at the end of the Maelstrom would be my home. I did that other places, but those are the 2 I can really remember doing it with.
My mom and I decided long ago that the brick building on the left and the one next door with the tarnished, copper-roofed bay window are our Disney flats :
I pick Disneyland. And I want the suite over Pirates as my private home. Or I'd take one made over for me above the shops in Adventureland. Oooo...I just thought of it...I want to live in Tarzan's Treehouse but they have to bring it back as Swiss Family Robinson and I want that water pulley thingy back too. The Tarzan figure can stay!
Our family has this conversation every time we go to WDW. I'd live in the little run-down hotel overlooking the river in Asia, DD9 (of course) wants to live in Cinderella's castle, and DH is still torn between FW in Epcot and somewhere in DHS.
So...obviously it will never happen for us, even if it could, because we can't agree on one place to live.
