As diehard DIS fans we did our first NON-Dis park trip this week, just got back today. We decided it was time to FINALLY check out SeaWorld.
To answer some of your questions, first I have to thank some of the posters on this thread regarding advice about SeaWorld.
I wasn't sure which tickets to go with so I waited until we got there however it was no problem purchasing them as we purchased them at the electronic kiosks located near the "side" entry gates (a little less people traffic there). We walked right up and it took about 5 minutes.
We did make it a point to arrive by 9-9:15 so we also go lucky with parking and weren't too far from the gate area.
I think the Shamu kiddie area would be an enjoyable place for your toddler. The Dolphin Cove is also neat but your toddler may have trouble viewing because of his/her size. You can feed the Dolphins and pet them, but you'd have to pick up your toddler and lean him/her over to enjoy this.
We saw almost all of the shows in (2) 1/2 days. Keep in mind it's real busy right now. In a month, I think it won't be quite as busy. We found that we had to get into these shows a good 1/2 hour prior to showtime which can be a long wait for a little one so you might want to bring a small distraction of some kind? The stadiums sell food, so this would be a good snack time.
I noticed there weren't many shows in the morning. Pets Ahoy, the Sea Lion Show and the first Shamu show had 1 show before 12. We made it a point to see the first Shamu show because the next show wasn't until 2:45. Pets Ahoy is a really cute show (my 8 yr old dd loved this - we had to do it twice! LOL!) and it's inside, but get there early - a 1/2 hr before to get a good seat or even a seat at all! Fills up quick!
We ate at Mama's Healthy Bites (I think it was called) and The Spice Mill. Most of their counter service food is premade but it's ok. I did notice the CS places got packed by 12 and the lines were long, but they moved. It was getting a seat inside that was tricky.
Advice- plan 2 days here so you're not going from show to show unless you plan to spend a whole day which can be a lot for a toddler especially in the August heat. Don't have "expectations". We are major DISNEY folks and although I tried not to, I had this terrible habit of comparing to Disney. The employees are different than Disney CM's. It's a beautiful, fun place to visit-but there are definitely "little" things I noticed that would have not been noticeable at Disney parks.
From a first timer to another first timer, enjoy, the shows are clever and exciting. We'll definitely go back!
BTW, we stayed at SSR for the first time this trip (and loved it)--and I was shocked how close Seaworld was. It was under a 10 minute drive going the "back" way.
