I think you should be allright when you know where you are going, I would do it myself.
It's the perfect time though to bump into intoxicated obnoxious party goers, but if you're not one yourself they will probably not be interested in you.
I'll be the contrarian on this subject. If you are two strapping fellows which look intimidating to any potential trouble makers lurking around I personally would not do it. As is emphasized on many threads Amsterdam is a relatively safe city but as a local we read the incidents of street crime which tourists don't. Your chances of getting into trouble are statistically extremely low and minimal but it's still not something I would recommend my friends and family should do.
I don't see a problem with it. It's all safe to do. Just take the usual precautions you would anywhere in the world when walking around at night. Stay in the crowded areas, avoid unlit alleys and parks etc.
Nothing to be worried about in my opinion.
Why not just get a cheap Uber etc ? Takes all the worry away! If I (F) means you are female, then i would get a cheap Uber in case of idiots inebriated etc .Edited: 21 August 2017, 01:21
