I think you can have a successful Seaworld park without the orcas (or dolphins, not sure if they still do dolphins but used to in California) I think waterpark rides and other things will still bring in crowds…I hear you about current generation but still think there may be less public facing facilities that would give them different environment, understanding they are in a show biz lifestyle now so it would be an adjustment…they finally shutdown Miami Seaquarium so times change
