I love Port Orleans Riverside. It's a beautiful resort. I prefer the Magnolia Bend side of the resort over the Alligator Bayou section. There's nothing wrong with AB, I just liked the theming of the antebellum mansions in MB. My favorite building location there was Magnolia Terrace. It is right next to the quiet pool, and not too far of a walk from a bus stop or too far from the lobby/food court restaurant.
I also like taking the boat to DTD from the resort. It's a nice ride on the Sassagoula river, especially at night.
