No experience of the school you've mentioned but you've done the right thing in researching it thoroughly. There are some great flight schools in the US but also some sharks. I got stiffed by one in California a couple of years ago when I went to do an FAA CPL. I subsequently found a brilliant one in Arizona.
The trick with the FAA writtens is to learn the answers to the questions like a parrot. Download software from
www.checkride.com. It costs about $20 to unlock the full question bank. You basically keep doing the practice tests until you get at least 90% EVERY SINGLE TIME. Don't even think about sitting the exam until you DO get 90% every time. Once you do sit the test having done this - it is almost impossible to fail it.
People often talk lots of nonsense about the FAA PPL. They'll tell you that it's easy / inadequate etc. Most of the people who say this stuff have no idea what they're talking about.
The facts are that the ONE written FAA private exam is undoubtedly MUCH easier than the JAR exams. The FAA private check ride though (which includes an in depth oral examination) is more demanding than the JAR PPL skills test and in my view requires you to demonstrate greater mastery of the aircraft.
If you are planning on flying in the UK when you get back here, it is essential that you get some decent training. Although you should be more than capable of flying an aeroplane when you get home, the airpace works quite differently over here and the RT is quite a bit different too.
You should have a GREAT time! Enjoy yourself!
