While daily earnings gained from Disneyland, including the rest of its theme parks are not publicly disclosed (and their particular attendance and other figures are somewhat hidden) you can speculate. A number of guesses point out that the theme park is earning more than a few million a day.
As reported by The Walt Disney Company, in 2016, the company generated approximately $17 ($16,974) billion from its parks and resorts segment. Therefore, the potential "daily" income would be around $46.6 million.
The parks and resorts revenues increased 5% from its 2015 revenue, or $812 million. This is due to increases of $631 million at their domestic operations and $181 million at their international operations.
