Warning

Be wary of third parties selling hotel rooms and registrations 
These companies give the impression that they are the official handling agency and deceive congress participants by using a range of tactics often including unauthorised usage of the IDC2024 logo. In frequent cases, congress participants have been led to believe that they had made a registration, to find out onsite that no registrations were made whereas their credit cards were charged.
We do not make any bookings for participants, we have a roomblock setup here: HOTELS IN DELFT – IDC 2024 (acm.org)
