Wrong. I don't like it because he is enriching himself by staying at a for profit enterprise where all those profits go to him.
I would have no issue if he used Camp David, a publicly owned hotel that offers government rates (the GSA has guidelines and every major hotel group offers this) or he went to his home like Reagan, Clinton, Bush and Obama did. The cost goes would then go to a place that does not profit him.
He has great profit incentive to stay/meet at places he owns. He pays himself, and also gives it free advertising from every major network and social media site.
And everyone was worried about ethical conflicts of interest with Clinton.
