If you are still thinking about TLL airport overnight - it is fine. I have done it 3 times without incident.
First time I went landside because I was tamely following everyone else. Several people were camped out there for the night, it was nice and warm and no one official showed any interest. I think the security opened about 4.00am.
2nd time I asked a bemused police lady if it was ok to stay airside and she said yes. 3rd time I didn't bother to ask.
There are some annoying announcements at regular intervals about keeping your luggage with you at all times. Plenty of benches to lie on some of which are softer than others. Didn't try the pods.
