Hi pete,
i underwent some training at aaa for a couple of weeks last year whilst on holiday and thoroughly enjoyed it. having flown with a couple of clubs in the uk i thought the aircraft were a bit 'tired' but i never had any problems with the pre-flight etc. the flying was great and it was easy to build up some good solo hours (flew every day). i think the place is run by a couple of brits but most of the instructors are yanks, which is no bad thing and i would say the quality of the training was just fine. location is great also with fantastic weather & scenery and the possibility of flying at reasonable altitude without worrying about height restrictions, but for those reasons i found it tricky re-adjusting to flying in the uk even after only a couple of weeks.
i think you are realistic giving yourself a month to undertake the course - just make sure all your paperwork is sorted well in advance (visa etc).
have fun whatever you decide to do
