Every year SeaWorld knocks Christmas out of the park. Now with the new Sesame Street area, they can really go the extra mile to continue to keep their title as Orlando's best Christmas event. I hope they will theme the Sesame Street area better than they did for Halloween, just some wreaths and garland would go a long way.
Additionally, it looks like they've got some new offerings in new versions of Pets Ahoy and a Sea Lion show. In the future, it would be cool to see them do a Christmas version of Dolphin Days ala SeaWorld San Diego.
