After several UK start stop attempts at the PPL, i bought the bullet this year and went to OFT in Florida and passed. Recommend the school, however:
Top tip: do the ground school before you go unless you've got a 'minimum' of 3 weeks on your hands.
Remember the weather isn't always perfect, build in some cloudy day time to your trip.
The VIP packages (2weeks PPL) DON'T WORK VERY WELL! I saw several people looking very disappointed by it all.
Good luck
