Madrid. Adults-Only concepts and female travellers stand for specialized segments with a growing demand in tourism – at least in Spain. On the Canary Islands, Adults-Only hotels have increased from one hotel to 30 today; in the Balearic region, there are currently more than 70 Adults-Only hotels. In addition, Adults-Only hotels can be found in more star categories meanwhile. "Spain is a world power in tourism. But we have to go for continuous innovation", says Fabián González Checa, a specialist in hotel innovation and partner of the business development agency Digitalmeteo in Madrid. Is specialization the lifeguard of a mature country? "It is the only way to survive", says González Checa convincingly.
