I will be having a long layover (11.30 pm to 7.30 am) at KLIA in a few weeks time. Arriving on Lauda and transferring to a domestic flight, with an 8-hour wait in between. I don't particularly want to use a regular hotel because there really isn't enough time to get the full benefit from it.

I'm not a member of the MAS FF club or anything, but I am a UA 1K and MM. Also, I won't be travelling with any checked-in baggage.

Any suggestions on where I could spend a few comfortable hours at KLIA waiting for my domestic connection, without having to spend a fortune?
