You're gonna have a great time, my best piece of advice is don't forget to get a map. It's hard enough to find your way around with a map when you're stoned, without one you'll be screwed lol Oh and watch out for the cyclists, loads of them everywhere in the dam, listen out for them ringing their bells!

For good quality/good value weed in the centre try central coffeeshop just across the road from the train station, it's got a got atmosphere and cool budtenders. Personally I don't like the grey area, I've only been once but it was pretty depressing, VERY small, uncomfortable, the guy who was working there wasn't very friendly and worst of all the weed was terrible. Maybe I just went on a bad day, but i don't see what all the fuss is about. A couple other coffeeshops I think are worth a visit are obviousley Dampkring, it's a cool place but gets full very early on so don't expect a seat if you go in an evening. I like homegrown fantasy too, it's a nice place to chill and they've got good weed too.
