For the OP, at your kids age I would vote CSR then POR.
CSR - We call is SW Tropical. Best pool, slide & overall water amenity. Beach areas and sand volleyball court. Food court upscale. Good transportation. Newest of moderates. Conventions kept the pool area less crowded when we have been. Great quiet pools. Three distinct themes for rooms. Little extras that made it nice. To some it is big, but we found the walking minimal. Some don't like food court, but we like the great food & selection.
POR - We call is relaxed southern charm. Good pool that the L shape lends to kids end and older end. Kids have always enjoyed it there when under teen ages. Great quiet pools, especially in AB sections. Good Food Court easily accessible. Boat to DTD. Central location. Two distinct themes will beautiful landscaping. Sleeping for 5 with trundle. Large resort but tight footprint, and walking never been hard for us. Transportation can be crowded and we tend to drive to parks from here.
POFQ - We have never stayed because it does not appeal to us because: while the pool is very cute, it is geared for young children and mine were never interested. Many love the smallness of the resort, especially with young kids. But for us it was too quiet (not that we are loud), we just enjoy the energy. Food court was sufficient, but no sit down. Share buses with POR and have the boat to DTD. A plus is they share all with POR so if you don't mind traveling back and forth you have access to all amenities. Resort has lots & lots of fans and I think it is great for older folks, those with very young kids or couples who want a small, quiet place.
CBR - Our least favorite. Has many diehard fans and it is pretty. Our issues: Very large resort with a huge footprint, too spread out. Was a long walk to main area. Long story short - very bad check in experience and was hours before corrected by management. Did not care for food court and ended up driving to other resorts to eat. Drove to parks, buses too crowded. Theme pool extremely too small for size of resort,small slide and small hot tub, and the kids like to use the main pool areas. Does have water amenities on lake.
