Singapore is compact, immaculately clean, and extraordinarily efficient — you can see the highlights in 3-4 days. Gardens by the Bay with its futuristic Supertrees, Marina Bay Sands' infinity pool, and the light show over the bay are unmissable. Sentosa Island offers Universal Studios, S.E.A. Aquarium, and cable car rides.
Chinatown, Little India, and Kampong Gelam (Arab Street) offer cultural immersion within 20 minutes of each other. The Night Safari at Singapore Zoo pioneered the concept globally. Orchard Road for shopping, Haji Lane for boutiques, and the hawker centers for food complete a well-rounded visit.
