Yes, hotels can technically track your browsing activity when you use their Wi-Fi, though the level of detail is usually limited by modern encryption. As the network administrator, the hotel (or their third-party internet provider) can see the domains (websites) you visit, such as google.com or netflix.com, and how much bandwidth you are using. However, because most major websites now use HTTPS encryption, the hotel generally cannot see your specific Google search queries, the exact pages you view within a site, or the data you enter into forms. This doesn't mean you are completely invisible; they still see where you are going and for how long. To maintain total privacy, it is highly recommended to use a Virtual Private Network (VPN), which encrypts all your traffic so even the domain names are hidden from the hotel's logs. In 2026, some luxury brands might use high-level traffic analysis to "personalize" offers, but for the average traveler, the tracking is mostly for legal compliance and bandwidth management.
