Info about Busch Gardens and more?

Heyy. I'm going to Busch Gardens on Friday. Yes, I've already checked the official site and I still need info about the park. Btw it's the 1 in Tampa Bay, FL. I can't wait!! I'm going with a few friends ( school field trip) and I do have to wear a school t-shirt which I will wear and shorts. Are there alot of water rides? Should I wear a bathing suit under my clothes? I'm leaving the school @ 7 in the morning and coming back around 7 at nite. Please no rude answers and best, most descriptive, helpful answer gets 10 PTs! Thanks in advance!
