Planning for a trip to Kuala Lumpur!

I just have to leave Singapore! HY's caught the bait as well, so we're leaving for KL on Saturday at 1030 where we'll catch a coach to Puduraya. Now we're thinking of places to stay and what to do (seems like nothing much to me as I've done some before) but I think the idea is to get the travel-as-a-backpacker adrenaline going.

Pondok Lodge
Pudu Hostel
Trekker Lodge

Petronas - by LRT
Berjaya Times Square - by LRT
Merdeka Square
Chinatown
Sunway Lagoon??
KLCC
Mid Valley Mega Mall
Parliament House
Petaling Street
KL Railway Station
