Have stayed in the north wing three times. Couldn't ask for an upgrade, because we were staying via Shades of Green and their rooms were only in the wings.
The south wing is closer to the pool, but the north wing in just a short walk. The north wing is closer to the food court, the bus stop and the walkway to the Magic Kingdom.
We have stayed in a parking lot view, 3rd floor. You get a great view of the MK and the monorail!
Stayed waterview, 3rd floor. Can watch Electric Water Parade from your room.
Stayed waterview, 1st floor. My favorite. Very quiet. Have a patio that you can sit on and watch the water and boaters.
Rooms are a great size! Lots of drawer space.
Any other questions, please feel free to ask or PM me!
