We're planning to have a vacation in Singapore but we just have limited budget (for a family of 4. My wife and I and our 2 kids). Where's the best place to go in terms of fun things to do, Historical landmarks, tourist spots, shopping and dining? Are there any cheap Hotels? How much would it cost us? (A rough estimate). I heard Singapore is quite expensive in terms of it's cost of living there. I'll appreciate a detailed answer. Thanks!
