We were just at Sea World the last week of August and begining of Sept. The only restaurant open for breakfast is Voyager. Yes, it is on the all you can eat plan. We had the all you can eat plan, and ate a full breakfast at Voyager shortly after the park opened. I think I remember seeing it was open for breakfast from opening to 10am. Then it switches to a lunch menu at 11am. We thought both the breakfast and late lunch at Voyager was good food. The servings (entrees) at all the restaurants are large.
