^ You're doing Bangkok all wrong.
Do it the Hallelujah way.
Check out at Midday the day before your flight. Save the money from your airport hotel and spend it on a nosebag and some horse tranquiliser off some dubious African down Soi 13, then drag your suitcase around Pat Pong, Nana, Cockatoo in Cowboy and end your sesh getting a tuk tuk to the airport from Soi 22 at 5am stopping off at some wonky pharmacy to pick up a few Xanax for the flight back and to drop off the 3 ladyblokes he's been pulling off all night.
Trust me, you'll sleep like a baby on that 23 hour flight
