I also have some questions about the buses, because I'm in Orlando this Summer and wanted to visit first Aquatica and then Wet'n'Wild. I saw that the I-Drive Bus just stops at the entrance of Aquatica and Wet'n'Wild, right? And can I buy the ticket inside the bus at the bus driver, or where? Because in Switzerland you can buy the tickets at the bus driver, but I don't know if it is the same in the USA or different.
Thanks for your answer in advance!
