5 star luxury hotel in singapore

One of my friends to go to Singapore Tourism, go after looking for a hotel to stay at, but found no vacancies, now also is the hot season of tourism, some hotels no empty room that is there, that he is to stay in five star is the best, so be sure to find, I told him 5 star luxury hotel in Singapore or many, does not have to be in a hotel so dead, then look for can be found, and I think he should put the hotel booked to go before, or else face problems like this is very troublesome, but I know a 5 star luxury hotel in Singapore is very good, just like he said.
