Hi, Luke,
The market does close noo-ish as Wendy said. We went to the market after we disembarked and settled in our day room at the Radisson (Jan 06). Many of the stalls were covered but a few remained open till about 1:30-2:00 (very few). We were able to get vanilla beans, extract, and a few more souvenirs. The market has an upstairs area too.
Used the fresh beans to make homemade vanilla ice cream - yummy! They suggested I put the used pods in sugar for future use.

Msheiny,
On Raitea we did the River and 4x4 excursion. it was great. We got soaked with a cloud burst while in the jeep. It was fun & damp! Don't forget insect repellant - they were hungry.

BoraBora - the waverunner around the island was one of our favorite excursions. Make sure you trade spots so that you both can experience the fun.

Moorea - we did AquaBlue & it was the highlight of our trip. Since we don't scuba, this allowed us to see things from a different perspective. Booked through the ship. They also took video and photos (available for purchase) but a great souvenir. Highly recommend.

Moorea - We rented a car for 1/2 a day and drove up to Belevedere for terrific views. The AC wasn't working so it was an adventure. No need to pre-book, there are different vendors there - we used Eurocar since they had a 1/2 price.

Have a great time!
Miriam
