I don't know if you have stayed at SeaWorld yet, but I will go ahead and answer.
I haven't taken this tour, but I have seen a part of it before. It involves visiting a backstage area of SeaWorld that acts as an animal hospital for rescued, injured, or ill animals. Parts of it may be similar to one part of the Behind the Scenes tour that is available to paying guests.
If I stayed at a partner hotel, I would definitely take advantage of this tour!
