We knew folks on our trip who had their luggage ransacked and a camera taken in Tahiti. We were told to put our bags in our room to be put on the bus and someone went through the bags.
If any of you are going to Tahiti, we found that taking your own cab with another couple from the post-trip day room adds a level of comfort to the trip. We took the bus and it was a cattle call and we found ourselves in a line at the airport in the heat. Those who took a cab, had their luggage in their control, got to the hotel quickly, avoided the lines.
