i dont like KL hahahahahaha i only like the choices of food...and shopping...but nothing compares to manila though, i heard it's flea market are air conditioned!! i am from Sarawak, Borneo so if you want nature hikes or cultural experience head here, my sister in law has a guesthouse i can hook u up
but if u like the skyscrappers and clubbing scenes then head to KL, awesome beaches in perhentian island or sabah island's, world heritage caves in mulu, air asia is cheap, everyone can fly! Tell me what u like and budget and i'll suggest some itennaries for you
