at one of a group of five hotels in the tourism region of Arade (Algarve, Portugal), an area
known for its beaches of “Alvor” and “Treˆs Irma˜os”, as well as for its typical fishing
village of Alvor, located at approximately 74 km from Faro International Airport
(Algarve). The hotels are all units belonging to the same Portuguese hotel chain, which is
at the same time the major group of the accommodation industry in Portugal. This group,
whose identity is kept undisclosed at the owners’ request, owns twenty-three hotel units in
Portugal and twenty-two abroad. One unit is a 5* hotel with 195 rooms, and four units have
a 4* classification with a total of 299 rooms, 13 suites and 132 tourism apartments
