While on my transit flight to Tianjin (and return), I booked a single room at Tune Hotel at KLIA-LCCT on line. The room cost me RM16.18 net without air-conditioned nor towels. The room is clean and with wifi facility. There is even a room with a few PCs with Internet connection without any charges for room guest at the lobby.
At LCCT you can either walk to the hotel which is quite near if you are not carrying any luggage, but I suggest you take the hotel coach which only cost RM1.00 one way. The hotel is really value for money and I strongly suggest anyone of you to book early to avoid disappointment if you are on connecting flight as the rooms are mostly fully booked !
