Yes sir, you can find €130 at the very cheapest in some random small town in Poland but who on earth would rather hour build in Poland than Florida?
The flight school owns the condo in Naples so that's why you get a great deal, plus a courtesy car, that's what makes it overall cheaper. You can forget about things like a swimming pool, a condo, a free gym, a whole free SUV and the word CHEAP in the same sentence in Europe.
You get something like a temporary FAA PPL permit you can fly with while the FAA sends out your FAA PPL and everything in regard to PIC time is perfectly legal according to FAA regulations. Not very professional of you to immediately accuse people of doing something illegal with zero evidence by the way, I just talked to the owner of the school and he said they have employees that make sure they follow every single regulation.
Usually people do hour building after being out for around 8 months doing ATPL theory exams so I for one, definitely needed 15h with an instructor to get back into it and get used to the busy traffic, different comms terminology and different airspace compared to Ireland which has about 6 aircraft flying in the whole country at any one time. Flying over there and flying in Ireland is a completely different game.
In regard to the 500ft, the point was that it was over Miami beach compared to doing it over some random beach in Europe that no one has ever heard of. I'm guessing you are from the States so it's probably no big deal to you but to people from Europe it is a crazy thought to visit, let alone fly over a place you have only seen in movies. I could have went to Croatia or Poland to do my hour building for the same price per hour, ignoring the expensive car rental and Airbnb, but the experience you get doing it in Florida for a European is a million times cooler.
