Oh, I forgot about DFW, they have some comfortable areas and youused to be able to stay in the nonrev lounge overnight with cots and all but not anymore. I also had to do LGA (not by choice, got stuck) and that was the first time I'd been somewhere where you couldn't stay on the secure side (at least at a major airport). I also slept a few hours in DCA, I only got about a 3 hour nap before I had to leave but it was also outside security. The police came 5 minutes before my alarm went off because they thought I was homeless. In LGA, one of the thinfs I didn't like was that they openly let the homeless sleep there and one of them had mental issues. Of course, by this time, I only had about 4 hours left in the night, so definitely not worth the hotel.
