Since the birth of tourism, Belgian Luxembourg and the French-Belgian coast have occupied a central place in the leisure market in Belgium and the Netherlands. Non-competitive, they share the same audiences searching for the benefits of the ocean and the great outdoors. Hungry for exceptional activities, tourists are constantly on the lookout for a unique and personalised experience. However, providers on both sides of the border are faced with a lack of time, hindsight, expertise and means to innovate and, from a marketing point of view, perform in the context of a digital revolution that is shaking up their activities. The TENDANCES project therefore aims to promote the heritage and the specificities of these two territories by developing complementary tourism products and services more adapted to current consumer trends. This consists of enabling any tourist project holder to obtain personalised support, keys to understanding and applying the concept of destination, and financial participation in the context of the creation or the development of an activity. The cross-border approach will optimise the competitiveness of destinations without losing any market share.
