We total have 9 adults with 5 luggage. I booked one transfer service company for my trip in mid of May, they quoted SGD 45 per one way from Singapore airport to Sentosa or SGD 30/hour (min. 3 hours) for city tour and it will be 13 seat car. I think they offered the price is reasonable.
They also can arrange Singapore to Legoland round trip service, I will share more information when I finished my trip.
