I live about 30mins from Prestwick so if you have any questions about it, just PM me. I'm doing my flight training at Prestwick and love it.
Ayr is very close to Prestwick so is Kilmarnock however these are just larger towns. Kilmarnock isn't the nicest of places to live.
Even if you want to live in Glasgow, it's only about 30-40min drive from Prestwick down the M77.
