Four hours isn't a lot of time... Clear imigration, get into KL center (70 km from the airport.), meet up with the quare one, do the business, back out to the airport...
Theres a ST hotel in the airport... Its not really ST in the mongering sense! I think the term used was "Transit hotel", for tired travellers apparently...
Maybe Missy could meet you out at the airport?
Have fun...
