We have those tickets as well, as will be using them at the end of April, 08. We really hope there is some sort of special we can upgrade to.
UPDATE: Ok, so this morning I called SeaWorld again and got a different answer. I was told that the the second day free special was ongoing. The very kind representative I spoke with went and checked with her supervisor after I explained what I had been told and she was told, also by her supervisor, that the second day free IS still ongoing and all you have to do is go to guest services window to get the second day free upgrade. Figuring majority rules, I called back again for a third time to see what their answer was this time. . . . ladies and gentlemen, the 2nd day free promo is continuing after all. With ANY single day ticket you are entitled to the upgrade. YEAH! Glad I persistently called back. . . something I learned on these boards. .. . keep calling because alot of time you get incorrect information.
