Rarotonga does not have the dramatic landscapes of the Society Islands, but many other great features. It has a reliable public bus that takes an hour to drive around the entire island. The Cookies speak English which seems to be important to many travelers. French Polynesians - obviously - speak French, but residents involved in tourism speak English as well. The native tongue on both island groups shares 60 % of its vocabulary, but that doesn't help me since I only speak ten words of Tahitian. The Cook Islands are less expensive than the French Polynesian Islands. Their currency is the NZ dollar. The Pacific Franc in FP is tied to the Euro.
