That is a tough one.
I always feel "at home" in the lobby of the WL. It just has such a familiarity for me.
I also have one of my most vivid memories from WL on a cool night during a November trip. Sipping coffee, watching the Water Pageant by the geyser with the framework of the three wonderful women (wife and two daughters)in my life framing the whole picture.
But oddly enough,I also feel at home in Cosmic Ray's (go figure) listening to the dopey show by Sonny Eclipse. I think it has something to do with a very relaxing moment I had many years ago when the park was emptying and I just sat there with my girls. Funny how some memories stick with you... like sitting outside Beaches and Cream eating way too much ice cream for a human, people-watching and daughter-watching...seeing my then-pregnant wife trying to put our 4 year-old on her shoulders by Casey's Corner while I went to get hotdogs our very first day ever in Magic Kingdom, in order to see what all the fuss was about at 3PM(wow, they have a parade at 3 o'clock everryyyy day -yes, we were real newbies despite the planning)...strolling through the MarketPlace with no particular place to go... waiting at the bus stop going anyplace, with a new adventure and memory every time in front of you...sitting back and thinking about all my wonderful memories transports me and I can always "be" at Disney anytime I want to.
