We love the resort and stayed in building three on our last visit there. Hoping to be there again this December and I think our only requests will be non-smoking, third floor. We don't mind the steps to the third floor and you get a little less foot traffic by your room when your on the top floor.
Some tips: The resort is small and you are only five minutes or less from pool, food court, bus stop no matter what building you are in. Building five is popular because it is the closest to the pool. We prefer something a little more quiet. Building four is closest to the food court and bus stops, but I think it is a smoking building. Building seven is closest to POR if you want to enjoy the benefits of both resorts.
I don't think you'll be disappointed in any room you get at POFQ!
