Okay, its a possibility that it could be crowded, I recommend going early morning Bout a half hour before park opening would be fine. If you go early it will be fine. I recommend taking a break between noon-2 p.m. I've learned that when crowds get the worst at Busch. But early morning and later afternoon are pleasant times to do touring And go early in the morning you beat us Florida residents, we always arrive noon or later haha!
And I say its a possibility because I've been on days where it should have been crowded and it wasn't. And I've been on days where you wouldn't think it would be busy and it was. I swear all of us passholders must have decided to all hope to Busch Gardens that day.
