We'll be there in November. Glad to see so many good things as I was having a hard time getting excited about POR (stayed at the Poly last trip). We are a family of 5 also. Is building 16 a good one to request? We'll have our car, so bus stops aren't important-would love to be as close to the food court as possible.
Buildings no. 14, 15, and 18 are closest to the food court, but as you can imagine everyone requests those buildings, especially if they are a family of 5. POR is the most affordable mod that allows a family of 5, so it gets filled up pretty quickly.
Next year, being close to the food court/main building/resort amentities/transportation is going to be a preferred category and will cost extra.
