Best known as a popular layover destination, most visitors to Singapore may not make it outside the world-class Changi Airport. However, the small island nation is one of the most multi-cultural spots in Southeast Asia, with something for nightlife lovers, shop-till-you-droppers, foodie fanatics and historical buffs. A Singapore holiday package can also be incredibly family-friendly, with the resort island of Sentosa home to Universal Studios Singapore, Adventure Cove Water Park and SEA Aquarium, as well as two golf courses and a two-kilometre beach.
