Stay for 30 hours, you can only stay in the transit hall of the terminal, and you can't step out of the departure hall unless you have a Singapore visa.

The third terminal of Singapore Airport is quite comfortable, with lounge chairs to rest, and the safety is absolutely no problem.

Suggestion: Bring toiletries, dry food, three-in-one instant drink (cereal) and disposable underwear.

There is free WIFI, free terminal internet access and watching TV.

30 hours passed quickly ~ ~ ~

I am a citizen of Singapore.

Have a nice trip ~
