The closest I got to this was working on the Ringling Museum
renovation in Sarasota. I am not sure how much is open to the public
but the Ca-D-Zan is quite a place. I am not sure if they let you up on
the 4th floor but the ceilings are about 50" high. It was for the
kids.
Never been there, but I got to hang out some on the circus train with
the performers and arranged interviews for them with the media. One of
the trainers was hand-raising a baby tiger.
