Alligator Bayou building 14 and Oak Manor are the two closest buildings to the main 'hub' of the resort (AB 14 is closer, but if you prefer the Magnolia Bend section, Oak Manor is the closest).
Alligator buyou bld 14 is much closer to the main bld than any room at Magnolia bend. We had requested Magnolia Bend last summer and they put us in BLd 14 in alligator buyou instead. It was really nice being so close to the food court/bus stop.
