I'm doing my PPL at a RAFFCA club as well, I've pondered the USA for some time now and decided that I'll stay in the UK and do it. At the end of the day it works out to virtually the same price!
As for weather well thats a different matter but I'm prepaired to wait it out.
There dosn't seem to be a problem with bookings of the planes at my club?? These people must understand why you are making so many bookings??
Take it easy
