Paul. I wouldn't hesitate to visit, even now. The picture of HK that you perceive on the television isn't quite the reality of day to day life here. Yes, on weekends there are protests, usually at selected parts of town. Advised well in advance. The rest of HK, life goes on as normal. To be quite honest, it's almost a form of entertainment at this point (not denigrating the seriousness of the issue however). HK is still one of the safest and most interesting cities on earth. Just a shame that it's cursed with a useless and tone deaf leadership. They deserve all the condemnation coming their way. If you ignore the needs of your population long enough, this is what you end up with. Regardless, come and enjoy HK. It's still a great city.
