Sea World isn't a park with a lot of rides,basically you have Kraken,Journey to Atlantis, Wild Arctic and a few kiddie rides and the small Shamu coaster in the Happy Harbor kids area.Kraken unless you go in a peak time will never have a wait of over 15 minutes,Wild Arctic and JTA maybe a bit longer but usually not too bad.The biggest thing when doing Sea World is to grab a park map when you get there to see what time all the shows are scheduled so you can plan out your day by the show times and leaving time to do the rides,eat and see the other attractions that don't have show times like the penguins and sea lions!!In my opinion Sea World is a much easier park to do on busy days since only a few attractions require making a line,the rest are shows that all you need to do is get there 15-30 minutes before showtime and grab a seat!!
