US and IOA draw 8 and 7 million each. You lose.Epcot, AK and DHS draw 10-12 million... you lose
Universal need a 25 percent increase to reach 10 million. There is a physical limit to how many people you can put in a park. And you can't just say what the limit per day is and multiply it by 365 because attendance is highest on weekends and holidays. The real number I have heard from people who know is that 12 million would be the maximum either of Universals parks can hold. It's the same problem Disney has with DHS. Without taking out the back lot tour DHS can't get past 12 million. Now if they took out the back lot tour and that crazy driving stunt show and took some of the parking lot they could increase capacity to a higher number.
There is no way either of Universals gates will pass Epcot unless Epcot falls apart or AK after Pandora and the other attractions are added. It will not happen because it's physically impossible. The only gate universal has a chance of passing is DHS but that dies once star wars is added. DHS will have a major addition but even if they did everything they can't reach a capacity of much more than 20 million and that depends on expanding into the parking lots.
