Most of these laws require consent prior to disclosure of such personal info (or unless such disclosure is required to provide certain services that cannot be opted out of). The hotel's privacy policy can also come into play as well, see https://www.hyatt.com/info/privacy-policy Clearly giving out your personal info to a "troublesome person" or a stalker (or actually anyone else) is not within the hotel's disclosure rights without consent. You did not give such consent and therefore your privacy rights were violated. It's not about applying a "stealth mode" at the hotel - these are basic privacy rights. If Hyatt corporate does not take this seriously, ask to be escalated to their data privacy team to discuss the issue.
