SeaWorld recently rolled out new ticket options that may be what you are looking for (I copied this from another website but only because the version on the SeaWorld site where you buy the tickets is so formatted it would have taken awhile to get into a decent format) -
ORLANDO, FLORIDA – Visitors and Florida residents can now choose from a variety of new admission products for the SeaWorld and Busch Gardens family of parks that provide more value and flexibility.
For tourists visiting Florida, the NEW “Choose Your Adventure” ticket option simplifies vacation planning so guests can enjoy multiple visits to four of the Sunshine State’s most popular theme parks. The program allows guests to customize their ideal itinerary and receive substantial savings for each additional park or visit — the more they visit, the more they save.
Guests can create their own favorite theme park adventure across the following four parks: SeaWorld Orlando, Busch Gardens Tampa Bay, Aquatica Orlando and Adventure Island Tampa Bay.
For example, when tickets are purchased in advance, online, special prices are as low as:
· One visit to any park – $79
· Two visits to any of the parks – $99
· Three visits to any of the parks – $109
· For the ultimate adventure deal — the new Length-of-Stay ticket provides 14 consecutive days of unlimited adventure to all four of the popular Florida theme parks, along with free parking at each, for one low price of $139.

There also are new values for Florida residents who are looking to visit all year long, with incentives for purchasing early in the year.
