A 20-minute boat ride from Cancún lies the small island of Isla Mujeres with its laid-back Caribbean ambiance, tiny streets lined with stalls, and street cafés in pastel-colored houses. Golf carts and mopeds dominate the streets, and although the island is only 5 miles long and half a mile wide, it still offers plenty of things to do and see. Everything from a beautiful palm-fringed white beach on the north coast to a dramatic rocky shoreline on the eastern side to a sea turtle sanctuary and the remains of a Mayan temple at the southern tip. If you're into adventure, then you should visit the Garrafon Reef Park & Beach Club, where you can go zip-lining, snorkeling, and kayaking. Lastly, a must-visit for nature and wildlife lovers is a tour to Isla Contoy, a nature reserve only inhabited by a few biologists and restricted to 200 visitors per day.

Berlin boasts the world's first computer games museum, which opened its doors in 1997. Since January 2011, the museum has been showcasing its new permanent exhibition in the fashionable Friedrichshain district. The exhibition has ingeniously converted the historic interior of the former East Berlin café, Warsaw, into a pixelated gaming landscape. It's the perfect spot to unwind, play some beloved video games, and delve into the history of the gaming industry. The Computer Games Museum is conveniently located on the Karl-Marx-Allee, the largest European cultural monument.
