  There is currently a growing interest in the study of sustainable tourism
experiences. Although the main dimensions of tourism experiences are known, the
assessment of attractions as a key component in sustainable tourism design has
seen little research. This gap stems from two primary challenges: firstly, the
complexity of each tourism destination, which makes use of heterogeneous scales
of evaluation; and secondly, the subjective nature of tourism experiences that
requires qualitative measurement scales and assessment. To overcome these
shortcomings, a new methodology based on fuzzy numbers is proposed, consisting
of a scale normalization stage, followed by an aggregation of the fuzzy numbers
that can be integrated into a Geographical Information System. This technique
is tested on the quantification of the tourism value of attractions for
sustainable experience in Santiago de Cuba.
