We just returned from DL/DCA and took one day out of our "All Disney All The Time" schedule to do one day at Sea World.
First of all the good things - Sea World is very, very easy to find (we were driving a rented car). We left Anaheim about 9 am and got to San Diego around 11 am. Traffic had its moments but generally wasn't a problem at all (yayy for carpool lanes!!).
Re: the shows, given the above comments, we were extraordinarily lucky and the schedules just "clicked" for us - we not only caught the shows we wanted to see but also lucked out and saw feeding time at the seals, the penguins and the dolphins. As for the other attractions, the Shark tank is absolutely not to be missed. Wild Arctic was great and my kids loved Cirque de la Mer (husband and I not so impressed as we just went to Cirque du Soleil two weeks ago!!!). And you must not miss the chance to touch a sea ray and pet a star fish.
We left around 6pm as we'd all had enough by then and didn't feel inclined to stick around for the evening attractions (plus, we still had to drive back to Anaheim).
Now for the negatives:
Seaworld's map and signposts SUCK!!! My husband has an absolutely brilliant sense of direction and we simply could not find our way around. We criss-crossed the park a couple of times looking for somewhere to eat. Also, no notification that one cafe was closed - very frustrating to traverse the entire park, finally locate the darned place and find that it's shut. There are lots of smoothie, popcorn, ice-cream and similar type vendors dotted around but very few places for "proper" food.
As for dining with Shamu, I was all set to make reservations before our trip but was put off by the cost (I don't recall what it was but remember thinking that it was a bit steep).
Which brings me to the food that we did manage to find - it was awful AND expensive (and bear in mind, I'd just spent 3 days in
Disneyland!!!). We ate at Shipwreck Reef Cafe and paid almost $60 for two plates of Jambalaya, a salad, a burger, a glass of wine (boy, did I need that!!!) and 2 or 3 soft drinks; I didn't enjoy the jambalaya one bit, the wine was positively evil and the "mixed" salad was almost all lettuce. On top of that, the seagulls were VERY agressive - I saw one whip a hamburger bun off a tray that was being carried by a grown man. I suppose this really isn't the fault of Sea World but still, it wasn't very nice.
And finally, the Turtles - most of the enclosures are a reasonable size but the turtles were crammed into a tiny pool; all of them were scrambling at the edges trying to escape.
All in all, DEFINITELY worth seeing but arrange food BEFORE you get there!
HTH and apologies for the length of this post - I guess I needed to vent - LOL!!!
