In summer 2012 we will visit Malaysia. Our last days we want to spend in Penang and Langkawi. I booked the flight return to Germany from Penang. Now we think we want to spend some days in Langkawi (swiming and snorkeling). So we must go back to Penang. We prefer the ferry. If we take the ferry we will arrive at 5.15 p.m. in Penang. The departure time of our aircraft will be 7.45 p.m. Is that enough time? Is there a bus from the ferry to the airport or it will be better to take a taxi ? How long is the distance between ferry and airport ? Is the ferry in time? Or it will be better to look for a flight from Langkawi to Penang ?
