Bush Gardens a long time ago had a Busch brewery on site. I've toured that one a few times, and then they just had a hospitably center with free beer until a year or so ago when they shut that down. I've been to their St. Louis brewery for that tour too.
I liked the St. Louis one because they had Bear Claw or whatever it is called. Could never find it in stores, but it was a stout.
I really would like to do Guinness or Bushmills if they do it.
