There's also some decent hire-car benefits in KL GE/PE - you can get free upgrades (on both) with Avis, free upgrades (on PE) with Hertz, and free #1 Club Gold membership with both.

For hotels, I've managed to get free upgrades at both NH and Inter-Continental hotels with GE.

And if you visit the Netherlands regularly the 10-miles-per-minute offer on the O2 mobile network (when roaming) is a fantastic little miles-earner.
