Hong Kong Disneyland and Zuji have partnered to allow online bookings of the two Disney owned hotels at the Hong Kong Disneyland Resort.
This means you can now book online, in Australian Dollars, and have your booking confirmed immediately. Previously, you could only book online directly with the hotel via unsecured email.
Just go to:

Click "Hotels", enter your dates, select country: Hong Kong, select city: HKD, and the hotels will appear in the list.
