Busch Gardens! and their water park!
Busch Gardens does the "pay for a day, come back all year" so you can keep going back if you want to, the water park does something similar but it doesn't include weekends, but you can pay to upgrade for a weekend day if you want to.
They have an awesome looking science museum that I'd love to go to, but will be waiting until my kids are a bit older.
There's an IMAX theatre there so any of the 3D movies out right now would be fun to go watch there.
Oh man, Tampa has a ton of stuff to do!
