Hi, I am traveling with 7 other adults. We will stay there for 5 days and then go to Gold Coast. Arriving at Sydney International Airport at 10am. Then we plan to get a taxi from airport to Central Station and buy a weekly MyMulti1 from there, and then take a train from Central Station to our accommodation at Milsons Point. I know about the airport train fee too so that's why I am not buying that to Central Station. Is there any better option?
We plan to go Taronga Zoo too which I know requires MyMulti2, but would it be better if I buy MyMulti1 and Zoo Pass at Circular Quay instead? I worked out that's cheaper than MyMulti2.
For departure to Gold Coast at 1pm, should I do the reverse? Which means taking the train to Central Station and then take a taxi to the Sydney Domestic airport?
