We used information from the International Dark-Sky Association to collate a shortlist of Dark Sky Places for which the geographical coordinates are publicly available. In order to rank these Dark Sky Places, we researched 3 data points: the size of the Dark Sky Place, the number of accommodation offers in the area and the median nightly price thereof. After obtaining the raw data, we assigned each data point a representative numerical value between 5 and 10, with 5 representing the lowest data point and 10 representing the highest data point. The hypothetical "perfect score" would be 30 out of 30. We used the following equation in order to calculate this for every factor:
Score(i) = 5 · (x(i) - xmin ) / (xmax - xmin ) + 5
Size: We used data from the International Dark-Sky Association to determine the size of each Dark Sky Place. The largest Dark Sky Place was given a score of 10, and the remaining areas were awarded a score of 5 or higher.
Accommodation offers: We used HomeToGo inventory data to find the number of accommodation offers in the vicinity of each Dark Sky Place. The area with the highest number of accommodation offers was awarded a maximum score of 10, and the remaining areas were awarded a score of 5 or higher. Data was collected in November 2021, availability is subject to change.
Price: We used internal HomeToGo data to find the median price per night for a holiday rental in the area between 1st December 2021 - 31st January 2022. The area with the lowest median price per night for a holiday rental was awarded a maximum score of 10, and the remaining locations were awarded a score of 5 or higher. Data was collected in November 2021, prices are subject to change.
