Need suggestions for a 4 day Malaysia trip!!!?

i dont agree with your statement that penang does not have unique thing.fyi ,penang is 2nd biggest city in mlysia after kl . and it is 2nd historical city in mlaysia . there is many places u can visit there .e.g , padang kota lama , tanjung tokong , tokong ular or batu feringgi . but is took about 6 hour to go there from kl . so if u wanted to save time so u better go to malacca . it is interesting as well .plus,u can save more time.
