In the larger project, of which this study is a part, the routine of vacation choice behavior has operationally been defined by four dimensions. The first part of the project was a quantitative analysis of the first dimension, the degree of repetitive vacation behavior in a 4-year period. As a result of this analysis eight clusters of Dutch vacationers could be identified, showing different (repetitive) patterns in the timing and spacing (domestic/abroad) of their vacations. In the second part of the project, the qualitative study, respondents from the eight clusters were interviewed on the three other dimensions of the routine of vacation choice behavior: the familiarity of the vacation, the adaptation of vacation behavior to changing circumstances and the extensiveness of the vacation decision-making process (see Bargeman, 2001). The focus of this paper is on this last dimension.
