Re. HKG Immigration Queues & response to my earlier message : Don't know how many travellers are aware that if you travel frequently to HKG, you can register your passport with HK Immigration desk after Immigration. They take your finger print, attach a bar code to your passport and you can then forget the immigration queues and use the automatic gates just like HK residents. You can also use the same gates leaving HKG airport. at the Macau ferry terminal and at the border crossing into China into Shenzhen.
