I've just seen that my post was truncated when I posted it. Unfortunately I lost internet access directly afterwards and couldn't review it. What I was writing was:-
Nr. divers = 6<8. Cost US$400 each, fully inclusive - dive/boat costs obviously, all food, all drink including alcohol (after diving is over!), all camping equipment, all park fees. No hidden charges. The only extra is nitrox 32& @ US$10/tank. Anyone not nitrox qualified can remedy that the day before the trip for US$100 plus PADI's card fee. Nitrox is highly recommended for this trip, to avoid bottom time being greatly truncated on second & subsequent dives.
Diving pattern negotiable with all the passengers, but expected to be two day dives plus a night dive on the first day, three day dives the second. A night dive will depend on weather/moon conditions. The Blue Hole will be the first dive of one of the days, unless no-one wants to do it in which case we will substitute another reef dive. This latter option would be my personal preference, as the reef dives on Lighthouse are magnificent and the Blue Hole is just a bounce dive to 130-140ft with not a lot to see.
