We have Sea World APs. So, we definitely think there's enough there to warrant going more than once. The last couple of times, we've just done quick one-day trips on our way up to
Disneyland (we have APs there now, too), but have previously spent 3 days there in an single week! On our one-day trips, we just hit the highlights - Shamu show, Blue Horizons, Atlantis, Wild Arctic, Sharks, Sea Turtles, Penguins, Pacific Point, Sea Lion show, tide pools and a couple rides in the Bay of Play for my little ones.
On the longer trips, we'll hit the Skyride, Skytower, more rides for the girls, the little aquariums, Pets Rule!, the Sesame Street 4D movie, spend more time letting the girls run around or ride rides in the Bay of Play and meet the Sesame Street characters (and the Shamu, penguin and otter characters), make it a point to feed the dolphins, etc. (I think we'll be adding Shipwreck Rapids to the list, as I think my littlest one is finally tall enough). If we go multiple days, then we tend to hit Blue Horizons each day, as well as the sharks, penguins and tide pools. Next summer, they'll be opening the new Manta ride as well, so I'm thinking that will have to be added to our list!
We may be sea creature fans though, I read a review of the Downtown Aquarium in Denver where someone said they were done in 30 minutes...we spent 4 hours there!
