So as weed selling to tourists is ilegal in Maastricht, me and my friends gave up and we are going to the Dam
We saw this NS Groepsretour e-ticket and, as we are a large group of 8, this seems to be a very affordable option. The ticket is 49 euro plus 2.5 euro for each addicional person (up to 10 persons), so 59 euro for all (around 7.9 euro each).
Did anyone used this card? This price is for go (Maastricht -> Amsterdam) and return (Amsterdam -> Maastricht), right?
