My own personal opinion of NAC is that if you want to get your PPL fast and relatively cheap, this is the place to go. I did my FAA PPL/IR/CPL and Multi there in 2004/5. It took me 5 months at a relaxed pace and at the end of it I had 250hrs.
I visited NAC just a couple of weeks ago and they have updated and replaced a lot of their equipment.
The staff there are friendly and helpful and will get you through as quickly as possible.
No flight school is perfect and you will of course run into small problems through your training, but having also spent time at three other different schools in Florida, from my experience you will have problems wherever you go.
As mentioned in other posts, Naples is a great city. It is extremely clean, has one of the best public beaches in the USA, is crime free and has some great bars and restaurants. In fact, I liked it so much that I just bought a house there !!
