Gates open at 2 but I'm not allowed to go to my seat until 3? Great job Nats. I pay this much for President's Club seats I should be able to sit there as soon as the park opens.
Kasten/Lerner want people to spend money for that extra hour. If you went to your seats that early you would start taking advantage of the "complimentary" food you paid for with the overpriced ticket.
Also Kings Dominion opens their gates at 9:00 but doesn't start rides until 10:00.
Same reason, you get to go in and spend money in their shops for an hour before getting on any rides.
