You know, I've been to Disney world a few times.  It's actually pretty easy to lose weight there due to spending 10~12 hours a day walking.  We'd usually have a normal breakfast, big ass lunch and leftovers for dinner that add up to a normal calorie count.  Couple that with tons of walking (16,000~20,000 steps a day) and we usually ended up losing a bit during that time.  But gawddamn the scootie puffs you see rolling around that place.
