French Polynesia
French Polynesia is expensive by anyone's standards, with over-water bungalows usually starting in the thousands, not hundreds, per night and a simple cheeseburger and fries from a street stand costing upwards of $30 in some places. It's best to know what you're getting into before heading out. If you can score an all-inclusive deal here, it's usually worth shelling out, as drinks are even pricier than food. Also note that if you stay on the more remote islands—pretty much anywhere other than Tahiti, Mo'orea, or parts of Bora Bora—you'll want to pay for at least half-board wherever you stay, as restaurant options can be extremely limited.
