A woman who answered the phone at Mar-a-Lago declined to share details about the party with a nonmember and said there was no press office to respond to inquiries. He hosted about 60 members of the U.S. Coast Guard at the course on Friday, played with U.S. Sen.
"They're some bad people", he said.
Mr Trump flew to his Florida resort on Air Force One a week ago, and his days since have tended to follow the same routine.
Critics said the boost in prices for Sunday's party and Trump's regular trips to Trump Organization properties - this is the president's tenth visit to Mar-a-Lago this year - show how he is using his position to promote his brand.
The president is also spending New Years Day keeping an eye on domestic unrest in Iran.
"It will be a fantastic 2018", said Trump, dressed in a tuxedo, as he entered the golden ballroom of Mar-a-Lago accompanied by the first lady, Melania Trump, and her son Barron.
Scott and Trump have always been friends. "People are much better off now not to mention ISIS, VA, Judges, Strong Border, 2nd A, Tax Cuts & more?".
Besides the daily golf outings, Trump has left Mar-a-Lago on two other occasions - for a Christmas Eve mass and for a visit to a local fire station. He's already sent his first tweets of the New Year, criticizing the governments of Iran and Pakistan.
Trump supporters said the extra hassle and cost will be worth it. "The people are finally getting wise as to how their money and wealth is being stolen and squandered on terrorism". On the subject of Pakistan, Trump tweets that Pakistan has given the USA nothing but "lies and deceit" for many years in spite of receiving billions of dollars in aid.
The President also "underscored the importance of Governor Scott's leadership in Florida, and the two indicated that they look forward to working together in the New Year".
