IF you are arriving on Saturday for the cruise I think you arrive around 7 pm and go straight to the ship. The markets are all closed by then. On the last Saturday with the new debarkation procedures you may have time to visit the market that morning. Check the post about it recently. I think the market closes at noon on Saturday.

Since you have 2 days at Bora Bora you may find shopping there to be more relaxing. Papeete has a larger selection but if you are looking for the usual tourist stuff like pareos, t-shirts, vanilla, oil, then Bora Bora had them too.

Actually we visited an ag school or farm of some sort and I bought a vew vanilla beans there. Where was that? I've been making Kaluha with them.
