I have been there done that, did my ppl in 17 days from 0-54 hours back in 1996. If you only have 2 wks by the time you arrive get settled and leave it will be 12 days maybe 13 if your return flight is boked for the evening time (late). Don't waste your time flying the extra 6 hours to California, keep it close and there are loads of schools in Florida, though California is way nicer to visit.
OBA seems to be the only place working hard to "get people done", be prepared to work your socks off and don't treat it like a holiday, you are there to get a certificate. I have been to the US throughout my training and used lots of different shcools and seen peopel come over from the UK and other parts of Europe and waste their time having a holiday and leave without their PPL only to have to pay more money and get it done back in the UK and that can take months.
Good Luck
