Mr/Mrs Sleepy,
I have posted on NAC before and so have a number of people here, therefore it may be worth doing a search, for the wealth of experience that exists here.
I have been to NAC twice now, and on both occasions, have thoroughly enjoyed my time there. I have only recently returned from finishing off the CPL hour building requirements.
With regard to the area of Naples, it is a nice clean town with lovely beaches, nice bars and great places to eat. Whilst I was there I stayed in the Condo's, which suited me, the area is nice and the people I have shared with have been great which has been a bonus. Cruise on down 5th Av on a Friday and Saturday night, for an enjoyable evening out
With respect to things you could do in preparation, I think you have pretty much covered it. If all your writtens are done, all you will have to do is concentrate on the practical side. It may be an idea to buy a 1:500,000 Miami sectional chart to start to familiarise yourself with the area and the surrounding airspace. You will find the airspace and the ATC service for VFR pilots, quite alot different from what you have studied in the UK. These charts are available from Transair pilot shop. It may also be an idea to get hold of the POH for the aircraft you will be doing your PPL on, just to get used to the speeds, systems and performance data. However, on saying that, they do tend to be quite expensive, and the school will have one which you can read in the evenings, once you have thrown the television out of the window, for having 83 channels of crap
.
With regard to the approach charts, I am not sure what you mean? If you are not doing an instrument rating, you will not require approach charts. If you are referring to airfield information such as the Pooley's, you can buy a Airport Facility Directory from the pilot shop at Naples Airport. This is similar to the Pooley's, in the respect it gives you all the necessary information on the airfileds you are likely to fly to in Florida.
Have a good time!
