Thanks for the information on PG diving. We booked on for the Marquesas cruise next year and then learned that the diving is limited on that itinerary, so we tacked on Society cruise at the front end. Three weeks might be a bit much, but it's a long flight! I communicated with Norman by e-mail - he was very helpful. My wife dives with a 50 cubic ft. tank - he indicated that they were available. Were the night dives worth it? I find that the older I get, the more attractive a drink or two and staying dry after dinner becomes!
