Sounds like you had the right attitude to wards the training, get your head down, get the exams done and enjoy the flying.
When I was at Oba 2006 the people that got stuck in and focused on the task at hand didn't seem to have any issues getting the course done. Funnily enough though the ones that treated it like a holiday were the same people that struggled the squeeze it all in.
My advice to anyone going to Florida for their PPL is to do the ground exams before you go. It may cost you a bit more to do this but you will be able to relax more and focus on the flying while you are out there.
