Vendors constitute an important part of the success of many festivals and fairs. Collectively, they may provide a central activity of the festival, both from a visitor’s point of view and that of the festival programming organization, yet are often overlooked or under-examined by festival researchers. This study presents the findings of a survey done of vendors at Sweden’s largest historic festival, Medieval Week on Gotland, which seeks to capture a more nuanced picture of the vendors and the possible factors involved in their participation. This study looks at distance travelled by vendors to the festival, years of participation, level of economic involvement, competitive awareness, and ‘tipping points’, or those elements which might be involved in a decision to not return to festival in the future. The implications for festival managers are discussed in terms of attracting and retaining a vital mix of festival vendors.
