Travelling to the Netherlands can be done by plane, train or car. Amsterdam Schiphol Airport is serviced by 77 airlines, with 289 destinations in Europe  and 110 Intercontinental destinations.

International trains from London, Paris, Brussels, and other countries may be an alternative for some.

Leiden is a small city. The conference venues are in the city center and clos to each other. Most transfers from your hotel to a conference venue can be done on foot or you can rent a bicycle!

Like in any city, eating out is very popular. If you have a particular restaurant in mind to visit I advise you to make a reservation a couple of weeks before the conference.
