Trump’s trips to his golf courses are very expensive and much more than Obama’s since Trump’s have been more frequent and usually requires Air Force One and all the accompanying security arraignments.
From a combination of an analysis from the HuffPost, the GAO or General Accounting Office, Politico and the Washington Post using costs from both Obama and Trump golf trips the estimated cost of Trump’s visits so far come to a range of $105 to $108 million. When you extrapolate the $105 million estimate to eight years, assuming Trump is re-elected, the total cost is over $340 million.
