There’s not too many overnight travellers here. T1 is the most comfortable spot and security moves everyone to an area with benches and carpeting. Travellers have used the benches near the restaurants after they closed; it’s unclear if this is the same area the security guards corral everyone. Some travellers report that security staff did a routine check of passports and tickets to make sure everyone are travellers. Lights are turned down at night. T3 has a lot of bed-like couches. For uninterrupted sleep, there are days rooms in the transit area, sleep pods in the public area and several nearby hotels that provide a hotel shuttle. See Airport Hotels in the airport guide below.
