We love PORS!! We have stayed in both Alligator Bayou and Magnolia Bend and loved each in its own way.
Alligator Bayou is designed to look like a southern bayou in Louisiana. It has lots of shade and deep porches on the buildings. The room furniture is "rustic" with beds made of "logs" and "quilts" for comforters.
Magnolia Bend is designed to look like Old South plantation homes and features gorgeous landscaping and fountains in front of each building. We stayed in Acadian House and although it was the furthest building from the Old Mill (the main building) it was a very short 3 minute walk through some absolutely gorgeous landscaping.
As others have said, the boat to DTD is a relaxing form of transportation and a first night tradition for us. We drive our own car, so I have no opinion on the bus situation at either resort.
I have never stayed at POFQ, but hope to someday when it is just the hubby and I. The over the top Mardi Gras theme does somewhat creep me out...don't like the giant parade heads and alligators everywhere. Also, the food court is much more limited than PORS.
As most others have said, I don't think you will go wrong with either resort. I suggest going to youtube and watching some of the video tours of the resorts done by allears. They will give you an excellent overview of the entire resort and the rooms.
Have fun!!
