The island state of Singapore is split into five administrative areas, of which the Central Region is by far the most relevant to foreign visitors. This Central Region, which is what we cover on Travelfish.org, is itself made up of a dozen or so areas, including the Central Area and Marine Parade.
The heart of Singapore's hotel accommodation, restaurants and entertainment venues are all within the Central Area — in fact probably the only time you'll find yourself outside of it is when you're heading to Changi Airport, Malaysia, the Night Safari or Jurong Bird Park.
Singapore offers an array of accommodation options, from budget hostels -- mostly in the Little India, Bugis, Kampong Glam and Chinatown areas -- through to luxury hotels, mostly centred around Orchard Road and the Quays. Food in Singapore is amazing. While it's not always cheap, you can eat for less than S$10 a day.
Use your savings to spend up on some of Singapore's impressive sights -- the museums and galleries are world class, the temples, mosques and churches a fascinating reflection of Singapore's multiculturalism and the parks exceptional. And while it's true that Singapore is Southeast Asia's most expensive city, you can still find some things to do for free. It's also a remarkably easy city to get around.
