Have a look at the Dutch National railways site which should give you train times on the night. There is an English language button.

Pim Zandergen (pim on the board) was thinking of going since he had tickets.

Bear in mind that the NSJF is pretty much a rugby scrum these days, so be prepared!

If you are coming back late on the Sunday night you should be OK getting into the hotel as they have night staff: however, you'll probably have to get a taxi back from Amersfoort main station as a) the trains to Schothorst only run to about 11PM and b) we might all be too pissed to drive and pick you up
