I am taking my 10 yo daughter to Sea World next year. What are the "must do" attractions and shows there?
When during the year are you going? There are different shows and attractions depending on the time of year you go.
The obvious don't miss shows would be
1) The Shamu Show "One Ocean"
2) The dolphin show "Blue Horizons"
3) And the sealion and otter show "Clyde And Seamore Take Pirate Island"
In the summer, these shows are offered, but there are special night time only shows too. For example, at night there is the Shamu show "Shamu Rocks". This show is different than the Shamu day show "One Ocean" and both will be offered during the summer. One Ocean during the day and Shamu Rocks at night. All night shows are different than the day shows.
During the Christmas season, there are Christmas themed shows. I posted a link a few topics down which details the Christmas themed shows and attractions going on right now at Seaworld.
As far as Attractions, a don't miss would be:
1) Dolphin Feeding
2) Manta (Roller Coaster)
3) Kraken (Roller Coaster)
4) Shark Exhibit
5) The New turtle and Manatee exhibit which includes a 3D movie. (This opens in the Spring of 2012)
Hope you have a great visit!
