My wife and I and another couple are going to Tahiti for a 7 day cruise on 3/11/06. My friend and I are considering signing up for the open water dive certification class. We will do all of the bookwork before we go. It still will involve instruction on the cruise, and includes 4 dives.

Has anyonedone this on the PG?

Will it take too much of our time on a 7 day cruise?
