We bought our DC passes for our March trip this morning. Through Discovery Cove directly, the price was $990.40 for 4 Day Resort tickets with Seaworld and Aquatica admission.
The exact same date through Undercover Tourist for upgraded tickets (Day Resort with admission to SeaWorld, Aquatica AND Busch Gardens with free parking at all parks) was $664.84.
A $325 difference
