4 of us require transport. Not too keen to use trains as carrying 5 suitcases between us and we are all elderly. Can anyone advise please?
Taxi or Maxi Taxi from the rank outside the terminal. The taxi supervisor will sort out the right vehicle for you. Just tell him/her how many people & bags you have.
Do NOT under any circumstances even think about thinking about taking an airport - CBD shuttle. They are uniformly dreadful, unreliable, grotty - and would be more expensive than a taxi for your group.
Taxi is the easiest and door to door.
Maxi-Taxi... will take all 4 passengers + luggage.
Cheaper than a taxi is Uber and for your group you would need Uber XL.
A normal taxi station wagon from the rank outside the terminal will do just fine.
