Dominique (did I spell his name right?) told me last year that he did not understand why people take the cert course on the PG. (Oh, he is one of the Dive Pros there - a truly great guy!!)
You have a one week vacation in paradise that costs quite a bit and you choose to spend a whole chunk of your time in class & studying?
It does not make sense!
What does make sense is what Mr MarnaLou suggested. Do all the course & pool work at home in your spare time THEN do your check-out dives off the PG early in your trip.
THEN enjoy some amazing dives with the dive team!
Have a great time!
