Grace Kelly's daughter, Princess Caroline of Hanover, married husband No. 1, Philipe Junot, in 1978, and they honeymooned in Tahiti. They're not the only royal couple who have headed to South Pacific island chain, either; Princess Victoria of Sweden and Prince Daniel, Duke of Västergötland, went to Bora Bora, among other places, for their honeymoon.
For some luxury island privacy of your own, Le Taha'a Island Resort & Spa has overwater suites and views of Bora Bora. Plus the whole place smells like vanilla. Fun fact: 80 percent of the world's Tahitian vanilla comes from Taha'a.
