I absolutly love Busch Gardens Tampa Bay, and while its not Disney its definitly a destination park. If you like roller coasters there isn't really a bad one in the bunch, Scorpion is a lot of fun, Kumba and Montu are wonderful. My husband LOVES Kumba and he has ridden over 400 roller coasters! I wouldn't ride Gwazi unless you really love wooden coasters and can handle being beaten up a bit. Tiger is the better side.
Besides the coasters the animals are very interesting, I really liked the hippo pool where you walk below ground are and able to see below water. I think that is near Crown Colony. The Wild Wings show is absolutly wonderful (if you like birds). I also recommend the Sky ride, and Rhino Rally. You can get a "fast pass-like" ticket (they call it a Quick Queue) for Rhino Rally there is usually an employee handing out return time tickets for free. Then there is no line or very little line to speak of.
SheiKra is insane, Jeff my husband loved it of course (coaster nut that he is). But you cannot be afraid of heights. All there is a VERY VERY VERY good BBQ restarant next to SheiKra called the Zambia Smokehouse, I am from Kansas City and ate there twice in the two days we visited the park. really very good.
Of course you have to visit the hospitality house, free beer is still served there.
What I would recommend is treating Busch like you would treat Animal Kingdom. Spend a lot of time, don't rush and enjoy yourself.
Personal opinion compared to Disney Parks, Busch is very much like Animal Kingdom, but Busch in my mind is still tons better.
