I go to Busch Gardens a lot. If you have a large bosom, you may want to forgo alpengist. Or if you do go on, use the special seats near the center of the train. The harnesses that come down and attach don't give much room to us large busted females.
You can test Apollo's Chariot before getting on. They have a test seat before you get in line. You shouldn't have any problem with the other coasters.
I have no trouble at any of the shows. Don't miss Irish Thunder if you like dancing similar to "Riverdance". They bring the dancers in from Ireland.
Pirates, already mentioned, is very good. Corkscrew Hill is a 3D simulator which in a small way reminds me of HISTA in Epcot. I say that because you are shrunk to the size of fairies and carried around in a box. It is quite bouncy though so beware if you are prone to motion sickness.
You can walk around Busch Gardens go in the shows and not go on any rides and still get your money's worth, they are that good.
The park is beautiful, shady, full of flowers and landscaping but also very hilly in some places.
If you have any other questions, I will be happy to answer them.
