"not to Easter Island but one similar to it"!?!

All I can say is "Yikes!"

Easter Island aka Rapa Nui is the most isolated inhabited island on the planet by geographic distance. The Moai (stone figures) are unique. Any island similar to it would be at least 1200 miles away (Pitcairn), wouldn't have the Moai, and have a dissimiliar culture...but it would be an island, that's about it. If Radisson/Regent ever mislead people with this kind of description, I'd report them to the National Geographic and the Association of American Geographers! (I'm a geographer, BTW).
