The document discusses how hostels can establish an atmosphere and plan activities to increase income both directly through activity fees and indirectly by attracting more overnight stays. It recommends that hostels identify interesting local activities, create an activities program including both free and paid options for in-house and out-of-house activities, and market the activities before and after guest stays to drive more bookings and longer lengths of stay. The Abraham Hostel case study is presented as an example of implementing these recommendations successfully.
