Hiring a car is very expensive in Singapore. However, an extensive bus network and the reliable MRT train subway system are both cheap and user-friendly and service all parts of Singapore. Electronic EZ-Link passes cover trains and buses and prevent the need to carry loose change for fares as well as giving a slight discount on standard ticket prices. The city also has thousands of metered taxis, which are safe, air-conditioned and surprisingly affordable, driven by helpful and honest drivers. The only drawback is the long taxi queues during rush hour. Many of the tourist attractions are situated close together and walking is a safe and pleasant option if you can handle the heat.
