Technically, yes, a hotel's IT department or Internet Service Provider (ISP) can see the domains you visit if you are using their Wi-Fi without any protection. While they generally cannot see the specific content of your searches on "HTTPS" encrypted sites (like Google or Amazon), they can see that you visited "https://www.google.com/search?q=google.com" or "bankofamerica.com" and the amount of data you transferred. In 2026, many high-end hotels use "traffic shaping" or "analytics" software to monitor bandwidth usage, which inadvertently logs your browsing history at a high level. To protect your privacy, the peer-to-peer "gold standard" is to use a Virtual Private Network (VPN). A VPN creates an encrypted "tunnel" for your data, making it impossible for the hotel to see which websites you are visiting or what you are searching for. If you don't have a VPN, at least ensure the websites you visit have the "padlock" icon in the address bar, but be aware that the hotel still knows which "host" you are communicating with, which can be sensitive depending on your destination.
