Don't listen to the voice of reason! You will end up in Wan Chai every late night/early morning (or midday?) anyway and that Wan Chai Novotel is just 2 blocks away from Neptune II.
Besides, the Wanch is perfectly well connected to everywhere by bus or subway, that hotel (and a zillion others nearby) is relatively cheap, and there is lots more to the area than the late-night partying and ladies of the night
Wan Chai Rule of Thumb: Do not step foot into any bar with curtains at the door and/or bikini-clad greeters unless you want to be easily scammed out of 1000's of HKD per minute, seriously and immediately enforced by big guys, so just stick to all the "normal" busy bars full of hard working entrepreneurial tourists ladies hoping you are stupid enough to fund their fake drinking needs and that you can't convert HKD's into triple digit USD to realize the excessively ridiculous rip offs they are attempting sell you on).
No matter where you stay, you will have to move around so make sure you at least figure out the MTR, Airport Express and Octopus system ahead of time.
