"Preferred"? No, not exactly. But they do break down the views by standard and waterview. We have had each. Have also stayed in AB and in Magnolia Bend. Would I pay the extra for a 'water-view' again? No, but a water-view room is the same price as a king bed room. And you could get a water view along with the king bed. That would be okay. But, since we got only a peek at the riverway, if we went out the door and hung over the railing, in our Magnolia Terrace room and had a view of the quiet pool in AB, I don't think it is really worth the extra just for a water view. The king bed would be worth paying extra for.
As far as which section do we prefer? I love the Mansion area. But, even tho we stayed in bldg. 35 (I think that was what it was) in the Bayou area, I loved the quietness there. Yes, it was much further away from the food court and the main bldg but we had a 2 minute walk to the bus stop for our area. And the walk in the morning to get coffee was so peaceful..bunnies hopping, ducks quacking. And it was only about an 8 minute walk. Mansion section is more formal and the bldgs. have three floors. AB much more rustic and only 2 floors.
