Go airport blow free aircon
Yes the airport is a very nice placeI always bring my kids to airport to study. My favourite place in sinfapore. Airport has so many things to buy, play, eat and shop. If have time still can catch a movie. I bring kids there 10 times in a month during school holidays Sometimes when kids r in school, I would sit at the cafe for hours. Weekdays r so quite especially between 8am -11am
Batam has nothing interesting.....at least IMO.Batam
