I don't knwo if you've seen this allready. There's a transit hotel in the transit area. It is nice and clean with attached bath but no wondows. For a night's sleep it is fine. I don't remember the exact price but may be in the 60-80$ range for 8 hours. You should check the website for the phone number so you can ask. Otherwise try travelasia.com where you can pick up an airport hotel for 40-50$ including transfer.
