When I went with my boyfriend it was about £700 each for flights (Cathay Pacific) & a pretty good hotel for 7 nights. I think I flew from Heathrow, can't remember. I'm sure you can do it plenty cheaper than that you if you're not fussy about where you stay. Although I wouldn't want to stay in the Chungking Mansions lol.
I loved it in HK though, it was fantastic. Almost everyone we spoke knew enough English for us to have a basic chat. Have a look at Wikitravel
for stuff to do. I really enjoyed the Ngong Ping 360 trip to the huge Buddha statue, and if you go to the Peak Tower get the bus up
, there are some really cool views (although admittedly quite a terrifying journey haha). We also went to Ocean Park which was quite good...pandas! All the museums we went to were pretty cool, and just generally walking around, going to the bird market and flower market, finding nice little restaurants, etc.
