Thanks DAvid. WE already bought on line the AETP 2 single journey. Meaning from the airport, we can already use the AETP from the airport to USA Hostel and vice versa? How long does it take from airport to the USA Hostel? Our check-in is at 2pm. our arrival time at Hk airport is 8am...Our plan is to deposit our luggage at the hotel first then use time before check in sightseeing. What suggestion can u give us for the 4 hours on the first day before checkin. WE want to visit for two days, Ocean Park, Disnyeland,Lantau Island, Giant Buddha,AVenue,symphony of lights, night market, times square, madamme tusaauds have a picture with disney characters etc. On 3rd day to Macau. thanks again.
