It's different because other presidents didn't then bill the government for the entourage to stay on a per-night basis for each stay. An added bonus for Trump was that his properties were also accessible to the public, so he got to make extra $$$ from people who wanted to stay close to where the President was. No previous president had that kind of an arrangement.
