Costs
Singapore is one of the more expensive Asian cities, especially for accommodation, and many items are priced at Western levels. On the other hand, with budget dormitory accommodation in plentiful supply, and both food and internal travel cheap, it’s possible to survive on £20/US$32 a day, though that would leave little for sightseeing. If you want to share a double room in a lower-mid-range hotel and enjoy one restaurant meal a day in addition to hawker-cooked food, your budget is likely to soar to £60/US$95 at least.
Note that Singapore has a 7 percent Goods and Services Tax (GST), which is levied by all companies except small businesses. Prices in shops include GST, but it’s not uncommon for hotels and restaurants to leave it out, quoting prices with “++” at the end. In this case, the first plus indicates that they levy a ten percent service charge (as all mid-range and upmarket hotels and restaurants do) and the second plus indicates GST on the combined cost of the room or food and the service charge, that is, a 17.7 percent surcharge in total. Where two prices are given for a museum or other attraction in this book, the second price is for a child ticket unless otherwise stated
