DEFCON conference attendees have a history of hacking hotel room keys, property management systems, filling pools with bubbles and doing all kind of mostly harmless but annoying shenanigans in hotels they reside during the conference. The conferences have changed a lot but something always happens. The right policy would be to always respect customer privacy and if they can't be trusted to behave, refuse them.
