Ravenair is an excellent school. I did all my training with them from first trial lesson to CPL and IR. They are well regarded within the airline industry and their AOC pilots seem to go on to bigger and better things very quickly. Like all schools there will be days when lessons are cancelled for whatever reason i.e. weather or tech a/c, but this happens at any flying school. At least they have plenty of aircraft thus making a tech cancellation fairly unlikely.
And in your case the geographical proximity is a definite bonus!
