I've no idea how well their system will work - but I do know I prefer staying in town instead of at by the KLIA Express, which is where the Hilton is. Le Meridien and Hilton are attached to each other. Either is brilliant for a late in, early out stay when you have an overnight between flights. But if I have a couple nights in KL, I find it bland. I would prefer to be in the more energetic city.
