Tips @ MACAU

Macau was geographically divided into three main regions: a peninsula and two islands. However, reclamation of the area between Taipa and Coloane has created a fourth region of Cotai and resulting in one bigger island with the peninsula.

Getting to Macau by plane:
Macau International Airport [3] (MFM) is off the shore of Taipa Island. It has basic facilities and a couple of aerobridges, but it is possible that you will park on the tarmac and take a bus to the terminal.

Macau's home carriers are Air Macau [4] and low-cost competitor Viva Macau [5]. While nowhere nearly as well served as Hong Kong, the airport is popular among low-cost airlines thanks to its low landing fees. Air Asia flies to Macau from Kuala Lumpur, Kota Kinabalu, Kuching, Penang, while Tiger [6] and Jetstar [7] serve Singapore, Cebu pacific[8] and Philipines Airlines serve Manila and Clark, Thai AirAsia flies to Bangkok.

Getting to the Taipa Island:
Bus AP1 plies a route between the airport and the Barrier Gate. Its route passes through several points on Taipa Island, and it stops at the ferry terminal on the peninsula on the way. It costs MOP4.20 per passenger, and MOP3.00 per bag. It has limited provision for baggage, and can be very crowded (you may not even get the first bus to arrive). Change at the ferry terminal for other destinations, the frequent number 3 bus runs from the ferry terminal and passes the Lisboa, Landmark Hotel, and Holiday Inn, or catch one of the hotel/casino shuttles which go the ferry terminal. The buses do not give change, but there is a currency exchange just inside the terminal that will change foreign currency into low denomination MOP.
Alternatively, take a metered taxi straight to your destination, but there's a MOP 5 airport surcharge plus MOP 2 for the bridge and MOP 3 per bag. Fares to the city center are around MOP 40-50, the trip taking 15-20 minutes.
