Volunteering is one of the fastest developing niche segments in the field of
tourism. There are different motives why volunteers tend to participate in megaevents and where they play an indispensable role in the organization of international
competitions today. FINA 2017 World Championships was Hungary's biggest
organized sports event ever which took place and where approximately 3500
volunteers helped the arrangement. The research has been focused on the
Hungarian helpers of the FINA event, regarding their consumption and expenditures
(accommodation, transport, meal, social program). For this purpose, an online
questionnaire was developed. Besides the relatively high number of respondents, the
survey was the first investigation about the championships and the previously drafted
questions were proved which highlighted the numerous parts of the FINA volunteers’
participation. The study’s most important result was that volunteers spent more during
the competition than in the average weekdays, so their expenditures contributed to
the revenues of Budapest.
