A step in the right direction
The powers that be at DragonCon issued a statement that can be found here
The long and the short of it is that they have entered in to an agreement with the host hotels to limit access to only individuals with con badges or hotel keycards after a specific time each day.
Makes me happy, but I'd also suggest that con goers get lanyards for their badges given the badge theft from last year with the clip ons.
