Yes, you have to be in Amsterdam during Intreeweek. All events of Intreeweek 2024 will take place in Amsterdam. It is possible to sleep outside of Amsterdam, just be sure to check whether this is practical or not (travel distance, public transport, etc.). In addition, we offer a limited amount of places to sleep in the USC sports hall at the UvA Science Park. You can purchase this option when buying a ticket for Intreeweek.
P.S. A bike is very handy to have during the week (and in general).
