London, England

One of the most cosmopolitan cities in the world, London offers visitors upscale shopping, dining and rich cultural stops. But London also provides travelers some very novel opportunities. London’s Natural History Museum holds adults-only all-night sleepovers that include trivia, music, a movie screening, breakfast buffet and craft beer and wine – all beneath dinosaur skeletons. Unique pop-up events organized by Events in the Sky brings London’s finest restaurants and their culinary expertise to a table suspended 25 meters in the air. Book a five-course murder mystery lunch on the Orient Express, or reserve a champagne tasting capsule on the London Eye ferris wheel for up to 30 guests, complete with five Pommery champagnes.
