Mousesavers indicates that AAA discount at the gate is $ 5 per ticket, and there may also be a discount on-line with AAA; you would do better on-line with Seaworld directly for adult tickets which is a $ 10 discount, as adults pay the kids price; if you have a Southwest Airlines Rapid Reward Card there is a 20% discount at the gate only on both adult and kids tickets. My understanding is that all of these tickets can get a 2nd day free, but it is best to call Seaworld and make sure. Once you have the ticket and enter the park, you need to activate the ticket inside the park before you leave that day for the 2nd free day.
