Our grandson (8) has an AP because we go often. But when he went with his mom, who does not have an AP, she booked the room in her name, but with an AP discount, because "a member of the party staying in the room had an AP" and that was OK with the resort. She has done this several times and never a problem. She was upfront and told them that it was her son (then ony 5) who had the AP and still, not a problem. Maybe the rules have changed recently, but we've done it several times.
