The shores of Lake Geneva have attracted visitors and invaders for millennia. The cheerful city of Geneva sits on the lake's western shore, lofty snowcapped peaks creating a gorgeous backdrop on all sides. The city is perfect for exploring on foot; hire a bike to venture further. At the top of any itinerary should be visits to Geneva's lakefront and its famous fountain, the Flower Clock in the English Garden, St Peter's Cathedral, Reformation Wall, Place Neuve and the birthplace of the UN.

Munich was almost completely destroyed in two world wars, yet it's managed to recreate much of its folkloric, Bavarian past. Oktoberfest is legendary, but you can visit the Hofbrauhaus any time of year for an immense beer. Olympiapark, the site of the 1972 games, is not to be missed (you can skate on the Olympic ice rink and swim in the pool). On a somber note, take time to visit the concentration camp at Dachau—it's an intense, yet unforgettable, glimpse into the not-too-distant horrors of the Holocaust.

Copenhagen is one of Europe’s oldest and most popular cities. It’s also one of the cleanest and most metropolitan. The dynamic Danish capital features progressive modern architecture, the must-visit Tivoli Gardens amusement park, stunning palaces, and all the activities and amenities you would expect in a world-class destination. Explore the canals and pretty narrow streets, appreciate beautiful old homes, and find great shopping and people watching on The Ströget.

Dubai is a destination that mixes modern culture with history, adventure with world-class shopping and entertainment. Catch a show at the Dubai Opera, see downtown from atop the Burj Khalifa and spend an afternoon along Dubai Creek exploring the gold, textile and spice souks. If you’re looking for thrills, you can float above the desert dunes in a hot air balloon, climb aboard a high-speed ride at IMG Worlds of Adventure or skydive over the Palm Jumeirah.

Port of Spain, the capital of Trinidad and Tobago, has the tall buildings, neon lights and crowded streets of many cities, plus a multicultural Caribbean character and a home-grown calypso soundtrack. The best-known event is the flamboyant pre-Lenten Carnival. Among the city's other offerings are cricket and football matches, year-round festivals, a botanic garden, malls, an art and history museum and historic buildings. Entertainment options abound, but be cautious after dark.
