Hi, I am travelling to Hongkong for 6 days. What is the best travel pass option?

Considering you are going to stay for 6 days, you are suggested to buy an octopus card, for it can be used in bus, MTR and ferry, even the tram to the peak and the cable car. With the card, you can get some discounts.

Do you refer to Ibis North Point Hotel? if so, you can take the airport shuttle bus A11 to the North Point Ferry Pier, and then reach the hotel within few mins walking.
Travel back to the hotel, you can also follow this reversing route.
