Price dosn't mean everything i took the cheapest option when i did my PPL. And have been paying the extra because of it.
Yes you can get cheaper than Naples but the planes are in good nick, the instructors are good (i flew twin there while hour building with Britannia). And they will keep completly legal with the visa side of things. The hotel that Naples have a deal with is great and there is a good bar just down the road from it.
Naples is a controlled airport which will get you into better habits for when you get home. If you can swing it ask for Gerald for your instructor he is a decent down to earth guy who is a true professional.
Sorry Richard for stuffing up your instructor planning but the lad is good.
