Living down here I actually avoid that part of town but with your kids being the age they are, I would suggest Magic Kingdom. I have not been there is many years but do enjoy going to Epcot every once in a while. Not the family thing to do but you can "drink around the world" at Epcot

I have heard mixed reviews about Disney's animal park but maybe somebody here has some input.
Discovery Cove is very cool from what I have heard as well. You can get a two day pass that is good for one day each at both SeaWorld and Bush Gardens in Tampa $85/child and $95/adult. If you go to Bush Gardens check out the Animal Adventure Tour. It is pretty cool and you actually get close enough to touch and feed some of the animals like the giraffes. I did it a couple of years ago but have heard it has gotten better.

You can also get a 5 Park Flex pass that is good for up to 14 consecutive days of unlimited access to Busch Gardens, SeaWorld, Universal Studios, Islands of Adventure and Wet N' Wild $190/child and $225/adult.

Another place to go that I think is fairly interesting is Kennedy Space Center. Not sure how interested your kids would be but I think it is pretty cool and if you wanted to go in the morning then you could spend the rest of the day on Cocoa Beach.

Just a few ideas. I will try to get some more info together for you.
