We stayed at WL last October after several stays at POR and PO-FQ. We did WL because we got the Fairy Tale Package so we thought we'd splurge. It was nice, but not worth the extra money to me. We really were unimpressed with the food court (Roaring Forks) and the Disney transportation. (Our first on property stay was at CBR, but I really didn't like it. It was years ago, before they redid the food court. Also, it rained a lot on that visit and we had a long walk to our building. So, with a 2 year old and a DH with the flu, it was a bad situation. I'm probably not in a good position to compare CBR just because of an overall less than perfect trip.)
PO-FQ is my favorite of all of those. It's smallish and very comfortable. You're never far from anything. We're staying there again in April. Transportation was always great. There is a boat to Downtown Disney from about 4:00 p.m. 'til very late (I'm assuming they'll resume that). I understand they are reopening on March 21, so we'll need to read the reports. With all the refurbishment, it should be wonderful and new feeling.
My 9 yo DD's favorite is POR. She is a little disappointed we're not staying there in April. We've always stayed in the Alligator Bayou section since I liked the theming better than the Mansions. Always in Buildings 14 or 15 - very close to the food court and the main bus stop. The main pool is larger and there are several quiet pools (which we never used). The main pool has a nice slide which may be a little longer than the serpent tongue slide at POFQ. The playground area is definitely nicer and bigger (better for older children) than the POFQ play area. The food court is also larger and there is a full service restaurant. (I believe that the full service restaurant at POFQ will stay closed.)
POR and POFQ are sister resorts, so you can use both pools, etc. One of the only places where pool hopping is allowed (only between the two). Also, POR is the place where you would rent bikes and also has a small marina and fishing hole. The marina at POFQ closed and I believe is staying closed. Although the boat to Downtown Disney is to be reinstated (it's just an extra stop on the way to/from POR).
I highly recommend either of POR or POFQ. Enjoy your trip.
