How to get to the city centre and/or Rydges on Swanston from the airport

There are basically two main options for getting to Melbourne city centre (where most of the hotels are) or to Rydges on Swanston from Melbourne Airport:

• a taxi (pickup outside the terminal building) will run to about $AU60 and take about 20-30 mins depending on traffic. Uber is also an option and there are pickup areas at the airport; a ride into the city is predicted to cost about $AU45-56.
• SkyBus offers an express service from the airport with pickup right outside the terminals, $AU 18 each way. It drops off at Southern Cross Train Station, which is an easy tram ride to Rydges on Swanston.
