The organisers, being born 'Arnhemmers', can point you in the right direction. The TCJA will supply ample quantities of tea and coffee. Addicts to Jolt or other specialties are advised that these are not generally available in the Netherlands. Bring your own if you're hooked. Operating an organisation like this is not easy and costs lots of money.
Payment is due at arrival in Arnhem.
We are not set up to do fancy stuff like creditcard payments, so please supply cash in Dutch guilders. An ISDN line connects us to the outside world. The internal Ethernet is 10base2 based, the FreeBSD box provides DHCP server functionality. So, by all means bring your laptop if you like. Arnhem is centrally located in the Netherlands.
