We just returned from the 1 Oct PG sailing. While we were more focused on the scuba diving, our on-board friends attended many of the activities you have listed above.

Raiatea - Many did the Black Pearl Farm adventure. We had originally signed up for a dive so did not take advantage of this, however, I would have selected this had we not been diving. Another guest did this and said it was ok, however, she felt the farm they visited in Bora Bora last year was better. However, if you know nothing about black pearls I think this would be great.

DO NOT MISS Motu Mahana on Monday. We were on the first shuttle and took the last shuttle back -- You will feel like you are in paradise.

Bora Bora - Off Road Adventure is Great but VERY off road. Take water - it was very hot and humid. Reports from on-board friends that Shark and Ray feeding was GREAT and all the men were really excited. EVERYONE was disappointed with the Motu (following Motu Mahana).

Moorea - I may be wrong but I believe they do the Lagoon discover and snorkeling near the Lagoonarium. There should be a lot of sea life there. Do not know anyone who did the Dolphin Watching, however, we did see some off the bow of the ship when we were entering Cooks Bay.

If your husband likes adventure, you may want to take advantage of the Waverunners either on Bora Bora or Moorea. It is pricey, however, my husband is very glad I signed us up. they are two-person waverunners and although I was very nervous, you see a totally different perspective of the island.

Hope this helps. You will have a great time no matter what you choose!
