Yes, we've been there twice. It was really convenient when we flew in to Tampa each time and we stopped there on our way to WDW. We went to the attraction the first time and spent a couple of enjoyable hours there. Now, my DH is an aerospace engineer and one of my DS's is really into airplanes too! But, it was interesting to me too!
Our second time there, we went just for the bi-plane flight and didn't do the touring. We also enjoyed that!
Let me know of any specific questions and I'll see what I can remember! We were there March 2008 for the tour, and July 2008 for the bi-plane flight.
