To add my 2 cents:

Yes, I agree with the above. You should do as much as you can prior to your trip. Classroom & poolwork, of course. But if you can swing the check-out dives, all the better! Imagine if they could not do your check-out dives for a couple of day on ship.

Oh, one more VERY important thing....if either of you take any meds & I mean just about anything! Have your home doctor write you a note saying that you are cleared to dive. It will save you LOTS of time. They are very careful on the PG.

Enjoy...I had some of the best dives of my life there!
