Did you go on their website and see? I know last year we were able to save $$ if we bought an online weekday pass. I can't remember how much. I would also check places like undercover tourist to see their prices. I think AAA had at one time a discounted price.
We are not frequent SeaWorld but I have got reduced pricing in the past.
The all day dining option was nice too. Since we were staying at Disney resorts and didn't have a dining plan, I think it was $30 for a day for an adult and it really was an all you can eat option. My husband and I are not that big of eaters but we ate to satisfaction and I think it was worth the dining ticket. Check that out too.
