"For instance: One of the programs described by the newly released GCHQ document is dubbed “Royal Concierge,” under which the British agency intercepts email confirmations of hotel reservations to enable it to subject hotel guests to electronic monitoring. It also contemplates how to “influence the hotel choice” of travelers and to determine whether they stay at “SIGINT friendly” hotels. The document asks: “Can we influence the hotel choice? Can we cancel their visit?”"
Yes, "SIGINT-friendly hotels."
