Just to compare, the price for Discovery Cove can be a little cheaper than Disney, especially if you have the ability to enjoy all the benefits ! (One day's food and for $ 20 more, the entrance to 3 parks (Seaworld, Aquatica and BuschGardens + transport to Tampa))
The first time I saw the entry price for DiscoveryCove, I thought it was too expensive. But then I just counted and with admissions to other parks "on the blue side of the force," it is definitely cheap.
