Just back from a month long break in HK. Punting in HK is relatively easy and stress free. I generally used the 141 site to find the building and rang the doorbell of all the available ladies. More than likely you will find yourself going past "massage" places and madams on these streets. Personally didnt try these places due to the attention it may cause. Most of these buildings are just part of a busy street so its a thrill going in sometimes.
The 141 site is good but most have been heavily air brushed so best to ring the bell to see the goods first. Most were pretty and you do get a variety of Asias finest. Didnt want to punt with Non Asians but sure you could find them too. You could easily spend the whole day just punting which I done a couple of times. Most of the 141 ladies are in Hong Kong Island but the MTR is so accessible that you can travel to other areas quite easily. The most I done in a day was 3 punts. Started around lunch time and finished around 7pm when meeting up with friends.
Now some of the bad points. The service is very vanilla. When at the door tell them how long you are after and what services you require. Dont be shy and use your phone to translate if needed. This will save you the misunderstanding. It was generally 1000 hk dollar per hour. You can do 30 mins but dont expect the girl to put much effort in. So you pay more you get better service as most said but even so I found the punts very vanilla and mechanical. You go in, shower together, maybe some light kissing, then its either massage or onto the action. Now i can usually last for a bit and this was a problem. Most after 20 minutes were saying you need to pay more because I wasnt finished even though I payed for the hour. I just ignored it and went on my business. You could describe it as similar to Romanian girls here.
Generally enjoyed my punting time there but just be realistic with the 141 site and tell them what you want and you should have a good time.
