My wife and younger daughter are currently stranded over night at the Newark airport due to an "Act of God". All the hotels around there have been grabbed so they have to spend the night in the terminal. Luckily, Newark is used to this sort of thing and according to the website above, they have cots stored away for this sort of thing.

As someone who used to travel a lot for work, I got used to always traveling with a microfiber blanket for this sort of situation. It rolls up into the size of a soda can but really helps. Coolmax Travel Blanket: https://amzn.to/3xNHqQz
