I prefer DL over MK for several reasons:
I love New Orleans Square, the shops, the look, smells and sounds plus the food is wonderful
I love the outside of It's a Small World. When I first saw It's a Small World in WDW I was so disappointed at the lack of exterior granduer for such a signature ride.
The Blue Bayou Restaurant inside of the Pirates ride as well as the entrance to Pirates is unique and I miss it when we are at WDW.
