Someone is with me for Genting!
Genting ropes in Universal - in line with the Government's 'wants' of a themed and people's place-to-go attraction spot for the majority ! Together with its sister company Star Cruise (the 3rd biggest cruise operator in the world - a global cruise brand), the combo is very likely to win both hands up. The route from HK, Australia etc..can enroute the holidayers into Singapore.
Harrah - unlikely
Kerzner - High possibility, it operates the renowned Atlantis in the Bahamas, but the Sentosa spot is probably preferred for the people's choice kinda thingy, so....
Sun - It operates the famous Sun City in South Africa and is listed in Forbes top ten Casino Resort...been there personally, a well balanced resort, with both high-end and budget travellers. However, i personally don't think it will win.
Eighth Wonder -
