I called the resort directly and asked. When I asked if they accomodated 5 the CM said no. When I asked if I could get the rollaway, CM said, "If you pay for the rollaway, you can sleep five."
We stayed at POFQ last October and made sure to get over to Riverside. Boatwrights was not open for lunch, so we didn't get to eat there, but we did spend one of our afternoons at the pool. DD 11 enjoyed it very much. Even DS 3 enjoyed the waterfall part. The boat service (which I understand has just started up again) to DtD is wonderful. (One of the highlights of our trip.)
We can't wait to stay at CSR in December. It is my understanding that the pool slide is great and it also has transportation to Boardwalk.
Good luck with your choice.
