I would have to say that anyone going to Nederland just for the smoke should really just stay at home, the difference in weed isn't that varied to warrant the cost of the ticket..
It is such a waste to go to one of the friendliest , prettiest and most fantastic places on earth simply to spend all your time shitfaced.
Get out and about and experience as much as you can , it is such an amazing place and even after having lived there for 12 years I still discover something new each time I go.
If you get the time Bevewijks Zwarte Markt is well worth a visit.
