BEagle, before you start saying how tired CFI's become I think you should take up the offer and go to this school unannounced and find out what the CFI's really think and how they feel.
Let me just say, being in this climate does not make you feel as tired as it does in the UK...Sweat yes, tired no..
The only people I have seen getting tired over here is the students, and I am not talking about the flight school mentioned...
It does sound from what Naples Air Center said and notice the spelling of centre, that the Instructors set up their own time with their students and that they are not forced into flying, it is totally down to them. I like that idea that way you can have your cake and eat it (regarding breaks for lunch)...
Happy Flying
