You can also explore the airport: butterflies, cactus garden, plane spotting, free movies, free internet, food, duty free, the slide, etc. If you go landside, there's a food court used by many airport employees where you can eat well and cheaply.
However, for these times, take the MRT to the city and have fun. If it were the middle of the night, there would be more reason to stay at SIN.
