This chapter provides a general discussion on the right to privacy from an international human rights law perspective, followed by a discussion of how the human right is implemented at the national level. It focuses on the accommodation industry, where guests can experience both a physical invasion of privacy as well as an invasion of privacy consisting of disclosure of personal data. The chapter also provides a discussion about privacy in the travel industry. In international public law, the traces of a legally enforceable right to privacy from ancient legal systems have evolved into a fundamental human right. Many countries have codified the human right to privacy as part of legislation at the national level. The Spanish Constitution for example protects the right to honour, to personal and family privacy and guarantees the secrecy of postal, telegraphic and telephonic communications. A right to privacy can also involve personal information, instead of an intrusion into the physical space of a customer.
