We just called SeaWorld about this the other day, my husband is military, they told him with military ID its free until the end of this year. His friend just got back to base and had gotten in for free, so we called to make sure.
So anyway, since its over this year we just purchased our 2-day tickets on the SeaWorld website. We hadn't heard about an appliation...hmmm. Good luck!
