I was flying from ICN-HKT, but there was an overnight in BKK. Our flight left around 9 in the morning, and we got there around 1am. For a few hours it wasn't worth the hassle of figuring out how to find a hotel. I was travelling with some pretty pathetic people (ill-advised spring break trip, I'm only 21) who chose to ignore my warnings that the airport would be freezing. We made our way to the domestic terminal, found a place to lay down... they started whining about how cold they were, said they wanted to find a different place to go. I ended up going with them before saying "forget it, be at the gate fifteen minutes before boarding starts in the morning, I'll meet you there" and slept on and off in BKK domestic arrivals for a couple of hours before heading upstairs, going through security and laying down on the benches near the Burger King... slept there as well.

I would never, ever recommend staying in BKK overnight, no matter how late your flight gets in! Definitely not a good place to be. Uncomfortable, cold, busy...

As for the twits I was travelling with? They arrived while I was waiting in line with some of the last people at the gate to get on a shuttle to the airport. Set up the rest of the trip.
