OK, well 1st there is theming: PO-R is old south with antebellum mansions with French Provential furnishings, and bayou cottages with rustic furnishings, and landscaping that ranges from manicured gardens, to rustic woodsy areas. There is a main pool with the theme of Old Man Island, and 4 quiet pools located between the buildings. It is a larger resort, more spread out, with more rooms. Some of the bayou rooms can sleep 5, as they have a trundle bed. There is a large food court, a full service restaurant, a game room and the boat to take you to DTD docks here. There is also a piano bar in the main building. There are 3 bus stops around the perimeter of the resort, and one at the main building.
PO-FQ is themed on New Orleans, with bright colors, imaginitive sculptures, beautiful gardens and walkways. It has more of a city feel to it. It has one pool with a great slide that the kids love, as they get to slide down the tongue of a sea serpent. The food court here, isn't as big, and there is no full service restaurant. There is a nightclub called Scat Cats that specializes in Jazz. There is one centrally located bus stop, and there are only 1/2 as many rooms as at PO-R. The layout isn't as spread out, making any room convenient.
It really is a matter of personal taste!
