The purpose of this study is to investigate the relationship between types of facility layouts on the difficulty of wayfinding in theme parks utilizing virtual reality techniques. Two hypotheses were formulated: 1) A radial facility layout in theme parks is easier for visitor`s wayfinding than a circular facility layout and 2) The influence of types of theme park layouts on visitor`s difficulty for wayfinding differs depending on visitor`s ability for wayfinding. To test the hypotheses, experiments were conducted utilizing a virtual reality technique. Two virtual theme park spaces, featuring the two types of facility layout were formulated. Other variables, such as total length of route and types of facilities, were identical. After the experiment, each student`s level of wayfinding ability was measured through a questionnaire. The statistical analysis supports the two hypotheses, meaning types of theme park facility layout influence the visitors difficulty for wayfinding, and there was a relationship between types of facility layout and visitor ability for wayfinding. The limitations of this study were identified and future research suggestions were made.
