I agree with Barry. It's a 1 and 1/2 day park if you want to see everything and spend some time feeding the dolphins and Sea lions.
It really doesn't matter what day you go. They have 2 thrill rides at the back of the park, and a simulator leading to the polar bear exhibit near the front.
Get there at 08:30am, they start to let people into the first part where you can grab a map and get past the photographers. Head to the left, you'll run into a rope. At 9am, they play the national anthem and then you can walk to the back and get walkon rides on JTA and Kraken. In the afternoon, these rides have a 1 hour wait, so do them first thing in the morning.
Now it's just a matter of seeing the shows, which is no problem if you get to each one 20 minutes before they start.
Go see the manatee exhibit, and then the 1st Dolphin show should be ready. After that, head to the Clyde and Seamore show. Get there 20 minutes before it starts, because the entire stadium fills up and they close it off. It's worth being there early to watch the mime, he's funny. Then you can head over to Shamu stadium and get a good seat.
For the polar bear exhibit, do the "by terrain" walk thru, because the simulator is one of those that makes you sick, and there is a line for it.
After you see a few shows, go to the Keywest area where you can feed the dolphins. 4 fish are $4, and you'll want to buy a few cups because they go fast. This is a good place to rest, have a drink, and watch the dolphins. After that, it's up to you on where to go next.
