I am going to Sea World on Friday, July 13 ( is that a bad omen?). I was wondering if the 2nd day for free is still in effect. What do you have to do to get in the 2nd day for free? Is there something special I have to do? This is my first visit in 20 years and I would love to have two days to see everything for the price of one!!!! Please be specific if there is anything special I have to do.
