Marc and Pipsters,
As far as I know, there are no floats available on the PG. We have done this cruise twice and haven't managed to make it to the motu off Bora Bora either time! We had so many excursions booked the first time that we just didn't get there. The most recent trip, we tried to get there for just a look, but while waiting for the tender, decided not to take the time since I had a massage scheduled and we would have just gone over and had to turn around and come back. We made that decision based on what a woman told us as we were waiting for the tender. Her opinion was this: the motu is fabulous--in fact she was on her way back (second day) after spending most of the previous day there. She is a water person--said the snorkling, floating in the water was the best, but if you were just going for "beach time", it was not that great. No chairs or lounges, no food, no bathroom facilities. I think there are "liquid refreshments" available. I really wish I had experienced it for myself, but there just wasn't enough time! One more reason why back-to-back cruises on the PG are almost necessary if you want to experience as much as possible without wearing yourself out completely.
This is taken from Ia Orana: "The Bora Bora Motu is a strip of white sand, isolated yet with an open bar, shaded palm trees and beautiful clear turquiose waters. Kayaks, volleyball and great snorkeling are available for your enjoyment. Beverages and fruit will be available. Please Note: We request that all guests stay within the boundaries of our beach to respect the privacy of the local residents. There are no rest rooms or luncheon facilites on the Motu."
Hope this helps your planning.
