We will be touring Busch Gardens Thurs 8-3-12 and Friday 8-4-12. My kids are major roller coaster fans and are super excited to ride all of the roller coasters at BG. Do you know, or can guess what the crowd level will be like on these two days? Has anyone purchsed the unlimitted Quick Que pass? Should I purchase it ahead of time or wait until the day of. I am nervous about buying it a head of time, as i see it is non-refundable. I would not want to spend the $200.00+ if it's going to rain us out. Any thoughts or tips?
