True. I earned my PPL at OBA and had to go through the old checkout and familiarisation routine with the local club when I returned. That said, I enjoyed it and was pleased to learn that the CFI thought that things were fine, despite an unhealthy trust of USA 3¬4 week PPL'rs.
If you study before you leave, the exams are easy and you can concentrate on and consolidate your flying. Even better, do the exams before you leave. (Extra cost though).
Going out without studying is foolish - stress, pressure and division of effort. Also, if you plan to visit the theme parks and drink every night, you may find you have not got your head in the right place and the cheap costs will become expensive in the long run as you fail to acheive the targets on time.
Stay focused and prepare and you'll be fine.
