ooh Hong Kong, why'd you choose that city? Everyone these days just talks about America & Europe, but not many Asian destinations.
HK is absolutely the great place for shopping, you can buy real items there much cheaper than here. Not to mention, the shopping centres there are massive, the numerous food outlets, are literally like downstairs from ANY hotel you live in.
If you don't really know cantonese, it's still very easy to blend in, since they speak quite alot of english. Menus are in dual language - English + chinese. Probably the best is the MTR transport system, its in English, Cantonese, & Mandarin. So travel is easy!
@Karooh: I think there is a requirement that you must have a Credit Average i.e. WAM ~ 65 + No fails. If there are fails or your WAM is less than credit average, you'll need some supporting documentation.
