What is the cheapest way to get from Nijmegen Central Station to Düsseldorf Weeze Airport and, after a trip of several days, back from the same airport to Nijmegen Central Station?
I want to minimise the cost, but the journey shouldn't take more than 2 hours and I need to be certain that I arrive at the airport on time. This means hitchhiking is not an option.
I have found a shuttle bus but it costs €18 for a single and €30 for a two-way ticket. I hope to find something cheaper.
