I regularly fly with FAA PPL holders wishing to obtain a JAA licence or JAA licence holders that have trained in the USA. Now I am not an FAA system knocker in any way. I respect and like a lot of their more practical approach with less bull s**t, however, one thing for sure that I can tell you in my experience that you will return and be 1). Poor on the rt 2) unused to such complex, cluttered and unfriendly controlled airspace 3) very unused to the weather. You will either seek no training and likely scare yourself or infringe CAS, or you will seek training and end up spending the same or more!
Nicer weather in Florida though!
