I've stayed at both and would choose the AB anyday over the Mansions. The Mansions are very nice, but my family enjoyed the "feel" of the AB. It's shaded, more rustic looking, great location to everything (pools, buses, food court, ect). AB is more of a theme where the Mansions are more of a nice hotel feeling. Both have the same great service, cleanliness and amenities, so it just depends are your particular taste.
