Amsterdam Coffeeshop Directory Forums

I'm pretty close to booking 7 nights somewhere within this time frame 12/8-12/23 and was wondering if anyone has any advice for things i may want to see or avoid during this timeframe. Any help is greatly appreciated. I'll be flying solo so hopefully I can find some cool people to meet up with.

First post and I must say this is a very informative and helpful site. Finally planning my first trip to Amsterdam, sometime in December. From United States by the way(New Jersey).
