Doesn't matter how close the lesson are together, it usually takes the average person over 50 hrs for the PPL. But you may be above average, so you'll have to see. Other option is head over to Bristow Academy in Florida and do your JAA ppl for cheaper. I know you'll have to pay for accomodation but at least you won't have any weather delays and you will be able to get it done quickly. Just a thought!
