This ETC and UNWTO Handbook on Marketing Transnational Tourism Themes and Routes aims at acquiring a deeper understanding of the transnational tourism themes and routes that are already proposed to travellers. Through illustrative case studies it furthermore provides practical guidance - especially for NTAa and NTOs - on the the creation and implementation of tourism routes, on marketing thematic tourism, including its development, management and promotion. The Handbook will enrich UNWTO's tools for innovation, and feed into the ETC's 'Destination Europe 2020' strategy, contributing also to the development and promotion of its VisitEurope.com Internet portal.
