Disney Hollywood Studios 9.6 million per year/26,000 per day average. Disney Animal Kingdom 9.5 million people per year/26,000 per day average. California Adventure 5.5 million per year/15,000 per day average. When I used to work there, they would give us an estimate of how many people would be there that day. Then later in the day they would tell use how many people were actually there.
Disneyland's estimated capacity is between 75,000 and 80,000 guests. When they reach this range, as they did on both 28 Dec 2010 and 29 Dec 2010, they will shut the gates and not allow new people to enter (however, if you have a hand-stamp from the same day, you will be allowed to re-enter). Disney California Adventure park has its own, completely separate, attendance capacity, estimated to be around 30,000 or so.
