We base our resort decision on the pool! We have four kids and the pool is very important to them. They all love the volcano pool, it's a great pool, so we stay at the Polynesian. They do not necessarily ask for ID when you are swimming like they do at SAB, but when we were there in June, we did see them ask a family from Fort Wilderness to leave.
As far as not knowing what the rules are, there are signs saying that the pool and the beach are for the exclusive use of guests of the Polynesian Resort, so it would be tough to think it was OK to use the pool if you weren't staying there.
