"Since his inauguration, Trump has taken seven trips to his estate in Mar-a-Lago, Fla., traveled to his Bedminster, N.J., golf club five times and returned to Trump Tower in Manhattan once.
Trump's frequent visits to his "winter White House" and "summer White House" are especially challenging for the agency, which must maintain a regular security infrastructure at each – while still allowing access to paying members and guests. 
Always costly in manpower and equipment, the president's jaunts to Mar-a-Lago are estimated to cost at least $3 million each, based on a General Accounting Office estimate for similar travel by former President Obama. The Secret Service has spent some $60,000 on golf cart rentals alone this year."
Wait...he owns the golf carts so why we paying to rent them?
