With no financial limitations, I'd live in an airship--a flying fortress basically. I wouldn't drive the thing around much--the weather gets windy and nasty in the winter so keeping anchored would be a good thing....
But yeah....it would be one massive dirigible. Big enough that I could have some room for parties, maybe a sauna even--I'd have to work out how much lift I can get from heated helium chambers, but hey.
^__^ It would just be nifty, to be able to go *everywhere* without leaving the house. Ever. *lol*
