The lottery suggestion wins.
This situation is really no different than people trying to get concert tickets to a hot show. Every local place had a wristband system for randomizing the "start" of the line, and they would sell in order until all of the tickets were gone. They would announce that wristbands would be handed out at (say) 8 AM, and there was zero advantage to camping out -- if you were there at 8 AM, you got a wristband and had the same random chance of being the first person to buy tickets.
Honestly, all of the people camping out for this kind of thing creep me out.
