Can I prepay a room at WDW with my AP discount for my brother and his family? We are staying DVC and they are staying off-property for the week at a timeshare and just realized they are short one night. I would like to pay for their room (somewhere close to us at BWV). Is this allowed? 

This is over nine trips in four years. However, some people have reported having to show their AP at check in. For various reasons, I really wish they would ask at check in! I wonder how many people have gotten the AP rate without actually having an AP?
