Have to agree with a lot of what FlightMedic555 said. We've sailed on the PG under Seven Seas, under Richard Bailey's company, and under Ponant. Under Ponant there is definitely a tightening of the pursestrings. Lower end labels on alcohol and wine. We had to explain that in-room bar setup was included in our fare. Food was ok - but understand these islands are isolated and most provisions have to be flown in.
Other than that - the ship is great. But the staff is WONDERFUL. I don't think you'll find a crew on any ship that is more friendly, knowledgable, and anxious to please. Oh, and they will be calling you by your name on the first day!
Reviews I've heard from other vessels sailing Polynesia are much less enthusiastic about the crew.
