hi..im asking 2 questions about Hong Kong travel pass

1. can i use travel pass to ride a buss or ferry..or even for peak tram...just like ordinary octopus card by top it up.

2, how you count the 3 consecutive days if you travelling for 5 days in HK.
If I buy the AE pass, does the first of the three consecutive days of unlimited travel begin on the day I use the first journey from the airport to the city, and do I need to use the return trip to the airport immediately after the third consecutive day in order for the return journey on the express to remain valid? or i still can use AE for return journey to airport in the day 5.

The AE looks like good value but I do need to make sure that the three consecutive days of unlimited travel are independent from the days I take the AE train to/from HK.

Any advice is greatly appreciated!thank you
