Just a quick one, try Lydd, I did and still do,

but the 300 mile commute is a problem

I live in Bradford West Yorks and use a wheelchair. Every time we go down to Kent I go to Lydd for atleast 1/2 an hour. Iam always made to feel welcome and the instructors are friendly. I can recomend all I've had. I did some T&Gs on Sunday in their 150, now I have 5 1/2 hrs 40+ to go
