If you need something a little easier on the budget than Raffles, the Carlton next to Raffles would be worth a look. We stay there every year for a couple of days on our way to Europe. All we are looking for is a clean, comfortable room with good service if you need it, as we hardly spend anytime in it as there is always so much to do in Singapore. Love the shopping and eating. If you would like some suggestions please email me. Second the Orchard Gardens if you love orchids, which I do. We use the Metro to travel around as it's so clean and safe.
