How to pass time in LCCT?

I will be traveling in about 10 days and my flight transit at KUL to CMB is about 5 hours by airasia. (I reach KUL at 00:45 and my flight to CMB is at 6:15). This is the first time I will be traveling in airasia, so first time to LCCT as well. I heard that place is like a pit and the only place you can relax is McD. Is that true? How can I pass time in there? Do they have WIFI? Please share your stories, thanks!
