5 travellers in HK ( 2 children and 2 senior citizens)

We 5 will be travelling to HK from 4th November to 12th November and staying on Pok Fu Lam Road. Our itinerary is as follows:
04.11. - Travel to Chi Lin Nunnery
05.11. - Science Museum, Kowloon
07.11. - Disneyland
08.11. - Disneyland
09.11. - The Peak & Madam Tussauds
10.11. - Ocean Park

Can you please suggest which pass/card, we could buy for such a varied travel for so many days? Which is the best option? And how much will it cost?

Thank you for your help.
