A) Is this airport 24 Hrs? B) How do they feel about passing out at the terminals for long lay-overs?

Yes

I was gonna say sleep.. Must make sure you secure your bags.

I see people sleeping here all the time. It's not against the rules. It is a very toasty airport too. They also have a paid sleep spot at the gym and possibly elsewhere inside.

Yes, they are 24 hours. Officially, I don't know how they feel about it, but I have seen people sleeping many times.

I've seen people sleeping. If you have a ticket they probably won't give you much trouble. Good luck.
