Public transport to Yin Yang and miscellaneous public transport prices
Getting to Ying Yang is quite easy, and reasonably priced. I have done it many times over the past years.
Take one of the Intercity trains from Amsterdam (or Utrecht) to Roermond. Any of the trains going to Maastricht will stop there, and there will be a few every hour.
From the Roermond train station, there are 2 public buses that would bring you to the Melick JFKennedy stop, which is about 15 minutes straight walk along the main road to Yin Yang. Average wait for one of the buses is about 15 minutes.
Cost of a day return ticket from Amsterdam to Roermond is about 50 Euros. Which is not much more than the about 36 Euros C Region day ticket that I buy at Duisburg or Dusseldorf covering most of the red carpet clubs.
For those interested in the latest public transport costs:
To get the Sharks from Frankfurt - day return ticket is 21 Euros. This includes the R Bus that stops outside Sharks. So, total is 21 Euros.
To get to Sharks from Frankfurt airport - Airliner price has gone up to 10.40 euros.
To get to Oase from Frankfurt - day return S5 ticket is 13 Euros to Friedrichsdorf station. From there, it is 15 Euros for taxi each way to Oase. So, total of 43 Euros.
