We went there a few years ago thru Qatar Airways Holidays Package...Tel: +974 449 6969 or visit www.qatarairways.com. We stayed at the Renaissance Hotel with our room overlooking the Petronas Towers...in KL, lots of places to visit, Batu Caves, Bird Park, etc...for nightlife, try the Bangsar area...In Penang, I recommend Mutyara Beach resort, they have lots of activities within the resort including jungle tours, water sports, and there's a butterfly farm nearby...also you could walk around Georgetown for a day...

Enjoy!
