My friend Liam and I (Jemima) arrived and set up base across the harbour from Hong Kong island in an area called Kowloon. The cheaper, more rugged side. Most travellers stay in a notorious building called Chungking Mansions, a high rise building home to residential apartments, hostels and offices, money changers, restaurants and shops mainly run by Indians. We had met travellers previously who had stayed at the place so we weren't expecting much but our dormitory actually turned out to be nice and clean and the man that worked there was really kind and friendly. One aspect of Kowloon which is difficult to ignore is the amount or pornography and sex toys available for sale everywhere which was pretty sleazy.
We planned to stay there for 9 days while we sorted out our visa for Vietnam and our visa to travel back through China in order to get to Vietnam. We had come from China with a single entry visa and Hong Kong is a separate country which, in our naivety, we hadn't realised until we got there. We ended up paying for another entry visa which lasted a few months or so, we found out later that we could have just got something like a three day visa just to cover our travel to Vietnam but there was a lack of information on this option!
