I went to Florida to start my PPL(H). It was a fantastic experience but I rather regret it. By the time you have sorted visas, transport half way around the world, accomodation and then converted back to UK license is it really worth the financial beneffit? I would have said not!
I wish I had stayed in the UK and learned here, the weather, traffic etc are totally different meaning it took some time to learn the ropes once I got back!
