CNS Layover?

[DrA]

I have an international flight into CNS which lands around 2350, and I can't get a domestic connection home until 0630 the next morning. I guarantee I will get hit by quarantine, so I predict it will probably take almost an hour to clear customs, so I'd be surprised if I was out of there much before 1am, and I'd have to be back there by 5.30am anyway.

Just wondering if the CNS domestic terminal is shut entirely overnight, or can I hang around waiting for checkin to open? Or will I need to book a room for the night in town?

Thanks in advance for any advice
