Hey Flydaddy,
I do have to disagree with the comment a lot of people make about returning to the UK and finding it difficult to fly in our conditions.
I did my PPL in Florida earlier this year, and yes it was just a bit warmer !! than the UK, but I can guarantee that you wont be caught up in some of the storms i did there back in the UK. Also they seem to allow you to fly in stronger winds over there than what your instructor would allow over here, I feel that im better trained at landing in strong cross winds than most people who have trained in the UK.
My advise is to do your training in the US, not only is it half the price, its a nicer place to be and also you can have a laugh at the same time. And you dont have the worry of your lesson being canceled every weekend.
Hope this helps
