Disneyland is 85 acres in size according to a Google search. So that's about 1000 people per acre if the numbers are right. An acre is a bit more than a square of 200 feet on a side. So each person had about 7x6 feet to stand in.
Of course, that 85 acres includes the buildings, closed areas, etc., which is a huge percentage.
Some interesting videos on Youtube.
