SeaWorld Orlando and Busch Gardens Tampa Bay just started offering all-new annual pass options that include a variety of new perks. Indeed, the new annual passes are now divided into four different categories: Bronze, Silver, Gold, and Platinum (this is actually not a new tier). While the Silver annual pass includes blockout dates, the other tiers offers unlimited access to the park(s), free parking, and much more.
