and again I will say so glad Disney has so many choices. Dh and I stayed in a king bedded room in Sept for our annivesary in the mansions section of Riverside. We felt it was quite a hike to bus stops and food court. but with no kiddos along it was okay. We did enjoy quiet pools that time and thought room was big enough with a King bed.
just returned from POR AB with kids along. IMO, we got the best building available for convenience Bldge 14 but still did not like the AB section at all. just don't like the decor at all but that is simply my taste. Also rooms with 2 double beds were just to small for our family and amount of stuff we seem to accumulate each trip.
We visted and swam at both Riverside and French Quarter. FQ was so much, cleaner, nicer, better cared for. Slide was lazy and slower and just awesome for our 2 preschoolers. Of course the pool just reopened a few weeks ago. POR pool was always crowded, always dirty, always hard to find a chair and no life vest for small kiddos available at pool (needed to go to marina for them). again, slide was fun (faster but long lines)but otherwise much prefer FQ.
FQ feels more romantic to me as well. more compact, quieter.
our other issue is the food courts. POR was again crowded, hum ho food and dirty tables. we did like the pasta one time and kids liked personal pizzas. We enjoyed the FQ selections much better. faster service, cleaner dining area. and milkshakes and beignets to boot.
about the king beds, just keep calling back. that's how I got our king at Riverside last time. (had never been to either resort and thought I would like it better than FQ at time!

)
oh well, only thing I can say about buses it there is absolutely no rhyme or reason to them at all. We would think okay, we got it and they would change it up. some days we shared some days we did not. never waited to long ever which suprised me, did last Sept.
love the boat to FQ from Riverside and on to DTD. very nice alternative to buses. Again, IMO it is a bit of a hike in the hot FL sun to walk if you are carrying anything much along (think kids and swim toys, and whatnot)
visted CB and CSR both just to walk around and see them this trip. CB pool is closed off completely. CSR is lovely, more deluxe feel, nice big pool, but do not like food court set up as much with a large family it can get pricey. altho selections looked so yummy and bakery items looked so good. store seemed bigger here too.
and those are my biased opinions from a trip we just returned from today!
