Judy McCluskey, agency principal at McCluskey International, said: "Despite the compact nature of Luxembourg, the country has a variety of landscapes and a diverse cultural offering that makes it a great family or weekend break destination from the UK."
Liz Moris, product and trade manager at Luxembourg National Tourist Office, said: "McCluskey International is recognised as one of the UK’s leading specialist travel PR agencies, which is why we are collaborating with them to grow our relationships with leisure buyers and media across the UK."
