POR and POFQ are about a 5 minute walk from one another. There is a sidewalk that connects them adjacent to the river. POR and POFQ share a boat shuttle to DTD so you can also take a boat shuttle between the two, as there is a stop at each.
Aside from theming, the differences are...
POR is about twice the size of POFQ. POFQ is more compact with only one bus stop, no table service restaurant, a smaller pool and pool slide. POFQ is great for younger kids because everything is close to all rooms. POFQ has a lounge that features Jazz music by Eliott Dyson. All rooms (except king bed) have two queens @POFQ because all have been recently refurbed.
POR has more bus stops, both counter service and table service, a bigger main pool area with a faster pool slide, River Roost lounge with Yehaw Bob, carriage ride location, marina with boat rental, rooms that sleep 5 in Alligator Bayou (not all have been refurbed so some have two queen beds and some still have two doubles), rooms that sleep 4 in Magnolia Bend (mansion section)--when completed some of these will be the Royal Rooms (for an added cost).
Both are great! You can use the amenities at both, regardless of where you stay.
