Want to share the wealth? Grab your nine best friends and book the Amandira, a new five-cabin ship that’s essentially a seafaring version of the Indonesian island of Moyo’s swanky Amanwana hotel. Expect to spend your days snorkeling through the archipelago’s coral wonderlands, and evenings sipping French bubbly while you drift over the Equator. Five nights from $45,750. This appeared in the August/September 2015 issue.
