The complexity and dynamic nature of travelling offers many opportunities for technological support. But printed guidebooks remain the typical companion, despite many weaknesses. Therefore, interviews with independent travellers were conducted. Results indicate the need to support dynamic changes of trip data and communication in networks as an important source of information for travellers. While knowledge created by planning trips and collected during travel is typically only accessible to close friends after returning, virtual communities offer the possibility to immediately share information and provide tailoring through a powerful social interface. But their technological support typically lacks structure and personalization. The paper concludes by proposing requirements for a tool for individual trip planning based on collaboratively created information and personal information spaces.
