Used the P+R system on small parking lots near Diemen and Duivendrecht in Amsterdam. Spaces are always occupied – the pass only works with trains; the metro is not suitable. It’s also crucial to monitor availability on larger parking lots. Sometimes, it’s more cost-effective to pay 6 euros for parking in Amsterdam than to combine it with a transit pass. Today, NS invoiced the full amount despite a 13 euro promotion for a three-month transit pass. The promotion worked for only one month, and now I have to pay the full sum. Called, they said it’s my mistake (accepted after) but couldn’t explain the reason for the full payment this month compared to the previous invoice. Asked to contact another employee later; perhaps they’re not interested in resolving the situation. In conclusion, P+R solves the issue of car availability in the city but not the problem of people getting from point A to B and does not address the money savings problem either.
