I guess I am a certified fanatic as you will usually find me leaving the DW in the dust as I briskly walk from attraction to attraction, or my aptly as my DW told my MIL after our most recent visit:
"No way can he have any heart problems the way he keeps going from sunrise to sunset. We must have walked a hundred miles in the heat during the week. I'm exhausted and he can't wait to go back."
As far as singing, or doing a little jig, that's "normal" for any WDW fanatic!
