I went to RSSC site and went to Melissa's cruise and they were all there.

Editing to answer some of her questions. The BB waverunner price for 2 people on one waverunner. Prices have really gone up since I was there. On my excursion, we stopped at an islet and walked from the leeward side over to the other side (bugs, biting like crazy, bring DEET)where the shoreline had waves and was rock, much different, and then had refreshments and continued on for another stop out in the middle of the water for pictures. Not sure the ATV/combo. That sure is pricey.

I don't think the Lagoonarium excursion is available any longer. Since the Cousteaus got involved, RSSC they no longer offers activities that involve dolphins in captivity, as I remember.

Le Truck is just a very basic sort of transportation. You could probably google it and see pictures. People often just rent a car and go around Moorea on their own, but you cannot go offroad. Not shore was the coral preservation/land safari and snorkeling thing is, where is it?

I have no idea what Raiatea is "known" for. I did the canoe ride and trip into the volcano. It was mainly interesting for what I learned about the many ways they use all the plants in daily life.

You have so many choices!
