I did my PPL in florida and i really enjoyed the experience...lots a nice weather, different flying experience, new people to meet, well recommend it. They should include your night qualification also wihtout extra cost. and a nice holiday.
However, coming back to the UK.....I feel that hour building, CPL should be done in the UK, Different air traffic, airspaces, experience on dealing with the weather here is a distinct advantage.
I would say experience foreign climate, but always come back to UK to complete your course...the experience is invaluable
