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.

Monte-Carlo is home to the celebrated Monte Carlo Casino. This glamorous palace is full of frescoes, sculptures, and features an astonishing gold and marble atrium—not to mention the main attraction—gambling! Steeped in 700 years of Grimaldi royal history, Monte-Carlo’s location is stunning, tucked between French mediaeval villages and the Alps. Take in a world-class opera or ballet, bask in the sun on Larvotto Beach or get an adrenaline rush at May's Formula 1 Grand Prix.

Mumbai (formerly known as Bombay), India, is famous for its chaotic streets. For bargains and people-watching, outdoor bazaars top the list of attractions. Popular waterfront destinations are Marine Drive, where visitors go to watch the sun set over the Arabian Sea, and the carnival-like Juhu Beach. More sightseeing options are the Gandhi Museum, in the leader's former home, and the cave temples of Elephanta Island. For tranquillity, Mumbai has many religious sites, lakes and parks.

The southern Thailand town of Krabi serves as base camp for exploring the province of the same name, a lush region of jungles, limestone cliffs and idyllic isles floating just offshore in the Andaman Sea. Buddhist shrines still used by local monks are tucked into the chambers of the town's top attraction, Tiger Cave. The riverside pier links travellers with ferries and longboats to the best scuba diving, rock climbing and white sand beaches on the coast.

Johor Bahru is the second-largest city in Malaysia and, with the opening of two major amusement parks in 2012, it is poised to become a major tourist destination.
