Which hotel is better and cheap to stay in hong kong??

Hi, as for the accommodation considering the service, transport and price, I recommend Dragon Hostel to you. It is a nice choice for budget travelers.

Ok, actually your trip should be three full-day duration. Here is the general suggestion of mine:
D1: Ngong Ping 360 and Giant Buddha - Disneyland
D2: Ocean Park - The peak and Madame Tussauds - Victoria Bay (you can enjoy the Symphony of Lights here at night) and Avenue of Stars
D3: Central - Sky 100 - Causeway Bay - Stanley Market
In the afternoon: China Harbor Shopping Malls shopping and Temple Street Night Market at night.
In the early morning of the D4, you have to leave.

if i dun wan hostel, still got other hotel intro for me , for a room can fix 3 ppl...
