Singapore can be seen pretty completely in 4 or 5 days.
Food Courts:
Great food is all around you in Singapore: Chinese, Indian, Malay, etc. It was definitely the highlight of my trip. The best part about it is that it can all be had for very cheap. I ate at one of the many food courts around town for every meal, usually paying no more than or for a delicious meal. All the food stalls are clean and safe, and you're almost always guaranteed that it will be top-quality food.
Little India:
This is a great neighborhood for everything Indian. In parts of central Singapore it feels like you’re in China, and then when you walk into Little India, where you could easily be in southern India. Bollywood music blasting out of shops, cheap Indian food, and a generally more chaotic atmosphere offer a nice contrast to the sometimes overly sanitized rest of town.
Botanical Gardens:
This is a refreshing break from the city, and it is quite close to the center. The gardens feature paths through forests of plants and trees from all over Southeast Asia, as well as an orchid garden. Admission is free, except to see orchids.
Shopping:
I’m not much of a shopper, but walking along Orchard Road and going in and out of the bright and modern mega-malls that line it for miles is fascinating. Another benefit of this: Singapore is always hot, and these mega-malls can be great to walk through for 5 minutes to cool off. Generally there’s one not too far from you no matter where you are in the city.
Quick Tips:
Onward Travel:
A great option if you want to save money when traveling north to Malaysia and beyond is the cheap express bus to Johor Bahru in Malaysia, just across the causeway from Singapore. The bus costs roughly US.50, takes about a half hour, and involves a border crossing in which you get off the bus twice, once to leave Singapore and once to enter Malaysia. Remember to keep your luggage with you, as the bus will sometimes move on before its passengers are out of immigration. Don’t worry; another will be on its way shortly to pick you up. From JB, you can get onward buses, trains, and planes for much cheaper than if you bought a ticket out of Singapore. You’ll see the biggest savings on flights.
Information:
At the airport and around town are several free guides to weekly events in Singapore, as well as free maps of the city, which are useful to pick up. The help desks in the airport arrivals area are also very useful. The woman at the desk actually gave me .20 to make a call to my hostel, which I found amazing.
Best Way To Get Around:
MTR (metro):
This is by far the best way to get around, as well as into town from the airport. The trains are modern, air-conditioned, and efficient, and on the newer ones, you have LCD screens playing movie previews, etc. Fares are cheap enough, especially from the airport, paying roughly .50 to get into the center of town. Instead of buying standard tickets, try to get one of the multi-ride cards, which require a deposit which you get back when you leave. They’re great because you just wave it past the sensor on any subway or bus entrance and it automatically deducts the fare.
Taxis:
They are fairly inexpensive and useful if going to outlying portions of the island (i.e. the zoo) but mostly unnecessary in the center of town.
Walking:
It’s very hot out all the time, so it can get tiring, but walking can be great for seeing the city. And when you get tired, there’s usually an MTR station nearby where you can catch the train.
