Yes, 8,000 SGD (Singapore Dollars) is more than enough for a highly comfortable, even luxurious, 7-to-10-day trip to Singapore for a solo traveler or a couple. For context, the average mid-range traveler spends approximately $200–$300 SGD per day, meaning an 8,000 SGD budget allows for a daily spend of $800 or more. With this amount, you can easily afford stays at iconic 5-star properties like the Marina Bay Sands or Raffles Hotel, dine at Michelin-starred restaurants, and enjoy premium experiences like private yacht charters or high-end shopping on Orchard Road. Even if you factor in expensive flights and frequent use of private taxis (Gratings/Grab), you would still have a significant surplus. For a family of four, this budget would cover a very comfortable week-long vacation including all major attractions like Universal Studios and the Night Safari. Since tap water is free and hawker centers offer world-class meals for under $10, an 8,000 SGD budget provides immense financial freedom in one of the world's most expensive cities.
