One&Only Kea, Greece
This chain has a well-earned rep for the highest of high end luxe and the new property is its second Greek venture. It sits 45 minutes by speedboat from Athens and is an all-suite affair - each with its own private infinity pool. The island itself is sparsely populated with little tourist infrastructure, so the hotel had to become a world unto itself. It accomplishes the task with a quintet of bars and restaurants - including a hidden speakeasy - and Bond Beach Club if you feel like a party. The island is also a major drawcard for divers and the resort’s dive centre can provide access to the quartet of shipwrecks that dot the coast. Still undecided? The resort’s resident archeologist can take you on a tour of ancient ruins, the spa is a dream and One&Only’s Club One features an indoor-outdoor fitness centre, a dedicated teens’ area, bicycles, as well as padel and tennis courts.
