Duisburg lives from Europe's largest inland port, and around Ruhrort, the Innenhafen and Rheinhausen, logistics, industry and the University of Duisburg-Essen produce a steady stream of business and project travellers. This demand is less seasonal than in a tourist city — it arrives week after week, often for several nights at a stretch and with returning bookers.
That very steady demand is ideal for the direct route: booking through a portal costs you 15 to 25 percent commission, even though the guest already knows your house in Neudorf, Hamborn or Duissern and comes back anyway. A fast site that is found locally and is bookable without detours anchors these predictable stays with you instead of the intermediary.
