Quick question regarding accommodation in KUL.

I have just booked a mileage run to KUL for a weekend stay-over. My flight arrives at 23:00 hrs Friday, and departs 05:30 hrs Sunday (yuk!).

This is my first trip to Malaysia and am unfamiliar with the KUL. I understand that the airport is about 80 kms from the city, connected by busses, taxis, and KIAExpress trains.

Because of the late arrival and early departure flight times, am I best to stay at a hotel on-airport? Which hotel would you recommend that is comfortable yet reasonably priced (around US$50)? A nice view of the runway would be a plus.

On a related note, since I will only have Saturday to travel to the city, what must-see places should I visit?

Many thanks for your help.

Latitudes.

For my part, I travel not to go anywhere, but to go. I travel for travel’s sake. The great affair is to move; to feel the needs and hitches of our life more nearly; to come down off this feather-bed of civilisation, and find the globe granite underfoot and strewn with cutting flints.
Robert Louis Stevenson (1850–1894)
