I would be shocked if Xanudu did not have coffeemakers. For some local flavor pick up a pound of Gallon Jug coffee and give it a try. Just check the package to make sure it's ground and not just the beans. Same price either way, about $3.50 US. Marina's should have it. Don't bother with filters for the coffeemaker, there are usually some left over in the rooms. If not, Marina's once again.
The filters are also quite helpful should one become seriously desperate, or perhaps just curious, and have to resort to the locally distilled vodka (specifically "Czar"). Run the stuff through a couple times and it removes most of the particulates floating in the bottle.
If the opportunity arises drop me an e-mail. "She Whom Must Be Obeyed" and I are quite interested in getting some information about Moorea.
