We went to SeaWorld a couple of weeks ago and while we did do a bit of sitting and waiting for shows it was actually a nice reprieve during a hot, hot day! We didn't mind sitting in the shade waiting a little bit.
Here was our day (without the special seating/rides pass); we stayed opening to closing but closing was at 9pm...

Kraken

We did not see Pets Ahoy, my children were not really interested although if we could have fit it in we probably would have just because, and we did not do Turtle Trek. We tried to head into Turtle Trek but was got scared because there is a sign saying something about planning on 30 minutes (not the wait sign, that said 15 minutes) and we got nervous because we had dinner with Shamu planned. We ended up spending that time shopping and spending a few more minutes with the dolphins which worked out fine but if I had to say one regret/thing we missed I would say that.
