Definitely Port Orleans Riverside.
Not your typical playground. Is designed with the theme of Old Man Island, lots of area to run around & lot to climb -- bridges, slides, swings, fort.
Also next to the pool bar & not far from the food court at all. Nice shaded area as well on a hot day.
Port Orleans French Quarter is not worth a special trip. Just your typical playground equipment. Also, gets very hot & can't slide as it is out in the open & sun beats down on it.
Have fun.
