One of the issues with supersonic jets (certainly the Concorde), is that their takeoff speeds, and required runway lengths are much higher due to different aerodynamics, about 1.5x of what's needed for a 737.
This means these VIPs might not be able to land where they want.
Another issue is that these planes fly higher and take longer to reach travel speed, which eats into the the travel time benefits for shorter flights.
