Possibilites I've got so far are:
1) Den Haag- On the fence about this one, heard theres some decent coffeeshops but don't know much about what else there is to see and do besides checking out a few government buildings.
2) Zandvoort- Been considering this on previous trips but never got round to going, this time could be the one. One definite pro is its proximity to Haarlem, would be fun to cycle there providing I know where I'm going.
3) Rotterdam- Again, been considering this for a while. Reckon its a place I'd enjoy exploring but would need to find somewhere to chill and chong at some point and I've heard a lot of Rotterdam shops are buy and fly only.
So yeah, still plenty of time to decide, anyone with suggestions or info please let me know.
Peace out
