I was just on the Sea World website and I have a question about the tickets. For single-day visits there are two tickets available . . . A Single-Day ticket and an Advance Purchase ticket. If you click on the Single-Day ticket "more information" it says that the ticket may be used as many times as you want in a 7-day consecutive period. Does anyone know if this applies to the Advance Purchase ticket too? When you click on the Advance Purchase ticket "more information" it does not say this. Anybody know?
