Hello
I can recommend NS Aviation at North Perry/Hollywood airport just to the west of Ft. Lauderdale in Florida.
I did my PPL there in Jan 2011 - I was then 51 so it did 'stick' - a very professional outfit - in some very, very complicated airspace - I have no worries about radios and airspace.
If you can make sure you get the low cost accommodation - they do commercial courses (the PPL, CFI, IFR......) thing as well as lots of we mere mortals doing their PPL.
I would suggest that Jan/Feb is a good time to do it as one does not get so much of the afternoon storms and buildups as one one does in the summer, but lots of nice crosswinds for landing practice.
Also - make sure you get the US training VISA and the TSA bla, bla, bla - just need it once - some people say they have ways around it - do not risk it.
The training at NS was very good - I bought an airplane 18 months later having no solo'd since the flight test, first solo three touch and goes (10 minutes) and then a 500 mile cross country through the Washington zone on the way down to Barbados.
Due to peculiar circumstances my airplane was stuck in the US for the past three years, only last week my first solo in three years Florida to Barbados - the training they gave me really 'stuck' - goes somewhere with 'commercial' pilot standards and complicated airspace - sets one up for life
