Kingron,
First of all welcome.
This really has been done to death on PPRUNE. Use the search function and you will read many different conflicting opinions.
In a nutshell, I have been to two schools you mention, Ormond and Naples. Out of the the two I would choose Naples for a PPL, however, I had no gripes with Ormond, but NAC is simply better in my opinion.
With respect to the exams, you can self study and take them when you get to the states if you wish.
Good luck, and you will have a great time when you are out there, it is really a lot of fun. Oh, and April is a great time to catch some really great weather.
All the best.
