I am considering a one-day trip to Penang Island. I tentatively plan to arrive at the airport early in the morning, go to Kek Lok Si monastery (Penang Hill), and then go to some sights in Georgetown before returning to the airport in the evening. I will be by myself. If there is relatively efficient public transportation between these locations, I can do that. Otherwise, perhaps a car rental would be be a bit more expensive but would allow me to maximize my time sightseeing instead of waiting for buses.
Any help you can provide with transportation advice would be much appreciated. Also, if I drive a rental car into Georgetown, is parking easy to do? Thanks!
