Whilst I'm sure LPL has very good FTOs, and the advantage of full ATC it has the disadvantage for the student pilot of having only one runway. Although some years ago (January 1983 to be precise) I started my PPL training at Keenair, the majority of lesson cancelations were due to crosswinds which were beyond my personal capabilites and delaying my first solo to a point which I was at the time finding frustrating (the arrogance of youth perhaps). After many such cancellations and 17 hours dual instruction, I went to Blackpool with its 3 runway configuration and soloed first day there, 26 years later I still fly from Blackpool but am a little more confident in crosswinds. My point being of course that you should expect more cancellations if flying from Liverpool than from (for example) Sleap or Blackpool with multiple runways. Grass fields also would probably result in more cancellations due to state of the runway in the winter months. It is however not how quick you can attain a PPL it's how good a pilot are you once you've got one that really matters. Whatever the trials and tribulations dont give up if it takes the rest of your life its worth it.
