Hi,
My partner and I will be in HK from December 7-10 (4days 3 nights). We got a deal from our travel agent that includes tickets, accommodations (Dorset Fareast) and land transfers (airport-hotel-airport). Our ideal itinerary is:
Dec7: Arrive at HK, 10am. Ocean park; night market
Dec8: Complimentary half day tour (included in the package); Then Ngong ping 360; night market
Dec9: Disney; night market
Dec10: malls, street markets, Jade market; departure is 930pm
Here are my questions:
1. Which travel pass should we purchase, an on-load Octopus card or the Airport express travel pass (again, we dont really need airport transfers since it's already provided in our travel package)? Which is more suited for us?
2. Is there a $50 refund if we opt for the Airport express travel pass?
3. If we purchase an Airport express travel pass and try to load it, does this void the unlimited 3 days use of the MTR/Bus etc?
4. Can we use an octopus/Airport express travel pass on City buses?
5. Offline: re: night/street markets: which street markets should we visit? (I read too many tourist traps articles)
Looking forward to your response.
Thank you!
