Re: Does Disneyland ever "Fill"? I mean close the doors cause of too many people?
It's the Fire Marshal who makes the call. And he has the power to close the entire Park and shoe everybody out if Disneyland does not comply with his order. It's a fire hazard when capacity has been reached. During the summer and during the upcoming Winter Vacation it will happen a lot so be aware, get there early and you won't get locked out. They will open it up as people leave, but might have to shut the gates again when the limit is reached. And by early I mean Opening, not noon. If you are a Disneyland Fan you should be there at opening anyway.
