A21 Bus Hong Kong

Hong Kong Bus A21 Stop - Prudential Hotel
Hi:

From Airport to Prudential hotel, I see on your route map there is a Prudential Center stop which is very close to the hotel. But I don't see the same stop name for return trip back to airport. Please let me know which stop I should go to for the return trip back to airport.

Also if I used my Octopus card for A21 bus, do I scan the card when I get on board or when I get off the bus? Or both? Please advise. Thanks.
