HolidayCheck AG has its own TÜV-certified online travel agency with around 150 employees and works with all well-known tour operators. From the first research to the travel booking HolidayCheck offers one-stop service. Company History The idea for HolidayCheck was already born in 1999. The private experience of a Konstanz student led to the idea of ​​HolidayCheck. The plan was to travel to the Caribbean. At the local last minute travel agency a corresponding offer was found quickly. But there was no comprehensive information about this hotel. The young man researched the internet and came across the private homepage of a Canadian woman who had collected votes about hotels in the Dominican Republic. From then on, he and his friends could not stop thinking about offering such service to as many hotels and holiday destinations as possible. The idea for the evaluation platform was born. Finally, in the summer of 2003, a report on RTL made for the big popularity boost. Today With almost 7 million written reviews (as of 07/2016), several million user photos and videos from more than 650,000 hotels in the database, HolidayCheck, the largest German-language hotel review portal, offers travelers extensive travel know-how.
