And there are some cool animal exhibits too, so it's not just rides. But the rides are definitely the main attractions, including three of my favorite roller coasters: Cheetah Hunt (a triple launch coaster), Montu (one of the top inverted coasters in the country), and Sheikra (a dive coaster where you hang over the edge of the first drop, only 3 of them in the U.S.). The park also has an incredible drop tower where the seats turn inward so you are facing straight down! Hands down, Busch Gardens Tampa has the best collection of thrill rides in Florida.
I'm pretty sure that Busch offers free transportation from the Orlando resorts, so that may be something you want to look into if you don't want to make the drive. It isn't very far though, only like a 45-50 min drive from Orlando.
