To clarify, we DVC members only have limited privileges to swim at other DVC pools. We don't have an all access pass to go swim at GF or Poly or Pop. And even then, as someone else said, there are many date restrictions, and one or more pools that do not participate (BLT, I think). When they build DVC at the Poly, I imagine the Poly pools will be off limits to non-Poly DVC guests, since it's one of the favorite pools on property.
No double standard. We're paying for the perk in our membership, and even then, it's extremely limited. Besides, our literature clearly states that we CAN pool hop....while other Disney literature says non-DVC guests can not pool hop. Whether someone believes that's fair or unfair is moot - there are rules and they are to be followed.
