Agreed. Badge checks in video rooms were extremely lax this year from what I experienced. Granted I had no issues in any of the video rooms but only three times did I ever pass any staff or volunteers at a video room door, only twice was a badge check ever performed - once on Friday and once on Saturday.
I don't know if it's a Convention Center restriction but I've said in the past that checking badges at the two entrances to the hallways for the two video room sections would minimize the amount of required staff. Additionally staff / volunteers that are supervising the video rooms would be free to remain inside to keep the videos running and not have to perform double duty checking badges outside while keeping an eye on the room inside. Four total badge checkers (two at the entrance to each of the executive ballroom hallways) could take care of this, one at each hallway during off-peak hours.
