By the time people get off that Air Tahiti flight they wont be at the ship until 7.30 pm at the earliest. The majority of passengers will be on that flight there is no way that ship will leave prior to all those passengers boarding.

There is no reason for you to board the ship at 3.00 pm if you dont want to board that early. My guess is after a few days in Tahiti you will be anxious to board. I love being on the ship early and getting settled in and unpacked. It is so exciting to get on a ship for the first time and start investigating.

Besides you can be enjoying your first dinner on the PG while all those coming in on the flight are just arriving.
