This is going to sound really weird, but here goes. I can't stand to drink the Florida water, but for some reason the water in the showers in the resorts, with its odd Florida smell, is something I really like! I guess it just says to my subconscious, "hey, all's right in the world...you woke up in Disney World!"
I also love the smell of the Norway shop, the smell of Rome burning, the orange grove and piney woods of Soarin', and (another really strange one on the lines of my first one) the smell of the much-maligned Nescafé.
Worst smell, hands down, is the lobby of Bay Lake Tower.
