I worked atPNS as a CFI up until about a year ago. I also did my ATP written at All ATPs there. Of course, I worked for their competitor (Pensacola Aviation) but I never heard anything bad about the ATP guys. The instructor was nice, (doubt he's still there though) they had nice airplanes, and they will prepare you for the ride. They always use the same examiner so they know exactly what the profile will be. It should be fine.
