Participants must book their hotel or other accommodation by themselves. Utrecht offers a wide range of hotels, appartments and bed and breakfast accomodations, in all prize categories, from large hotels until hotels with only a few rooms. Although September is not really in the tourist season anymore, we advise you to book your room nevertheless well in advance. Accomodation can easilily be booked via sites as Booking.com or Trivago.nl. Private accomodations can also be booked via airbnb.com. The fact that the name “Utrecht” refers both to the city of Utrecht, as well as to the province of Utrecht, may be a bit confusing. Make sure that you book in the city and not somewhere in the province!
Since Amsterdam is not far away from Utrecht, it is possible to stay in a hotel in Amsterdam and to travel every day by train to Utrecht. Keep in mind however that hotels in Amsterdam are more expensive than in Utrecht, and that trains to and from Amsterdam and Utrecht can be very crowded during rush hours.
