If I have an overnight (less than 24hr) stopover, what is my cheapest way on the AE? I read that the same-day ticket is only valid from midnight-midnight. I seem to recall that if I use a (non-tourist) octopus card, then it will be by 24hrs.
Is there a place I can buy a card at the airport? Last time, I seem to recall just getting on the AE and then paying when I arrived.
Does the RT work if I goto Central, but return from kowloon?
I think I kept my old octopus card from over a year ago as a souvenir. If I recall the balance was -30HKD.
