Yes I'll comment about Prestwick but I'll declare an interest as an instructor at one of the clubs there.
Two clubs; Prestwick Flight Centre; and Prestwick Flying Club. The former is effectively a business with all the advantages that brings. For example it is staffed 9-5 seven days a week; it has a large and varied fleet; good examiner availability; it's also where the local R/T practical test is held. Slightly more expensive than the club for landings and membership.
The latter is a private members' club. No full-time staff therefore contact can be difficult although the guys do try very hard to follow-up email and web enquiries. Slightly cheaper than the Flight Centre for landings and membership but more expensive on the flying rate (especially if you chose the Chipmunk!) Instructors all part-time but usually something can be arranged as they run a prime/backup pairing arrangment - unlikely that you'll ever fly with more than two instructors.
What may be a consideration for you and your daughter is the environment - at the Club there is only one female member I can think of, but another young woman does fly from time-to-time. There are more women at the Flight Centre and the ladies on the desk are very motherly. I'm not saying that the chaps at the club are a bunch of grumpy mysoginist middle-aged pederasts, far from it, but I can understand that the flying environment can be intimidating enough. Depends on the character of your daughter.
Web sites for both, if you Google. Good luck
