We are two couples heading to CSA next month. We were thinking about getting our PADI certification for scuba while down there. My question was in regards to the amount of instructors that available to teach. I wasn't sure if 1 instructor could accommodate 4 students or would we need more than 1 instructor. Also, If others are heading out for open water diving, will there be other instructors to teach us in the pool?

I just dont want to get there and find we need to be trained at different times, or find the dive staff is booked.
Thanks in advance for the help
