Overview The Grant Thornton Invitational is the only mixed-team event on the PGA TOUR and LPGA schedules. Sixteen players from each tour pair up and play for equal prize money from a $4 million purse. The format changes daily: scramble, then alternate shot, then modified four-ball. It runs in December at Tiburón Golf Club and The Ritz-Carlton Naples, Tiburón. Grant Thornton holds the title. On site Tournament week runs Monday to Sunday. A two-day Pro-Am fills Wednesday and Thursday, with a poolside pairings party at the Ritz-Carlton and an awards dinner with a private concert. Fans get Friday through Sunday on the Gold Course, a Greg Norman design. Saturday opens with Burn Boot Camp behind the 18th green and yoga on the 18th fairway. After play, Live Fest turns the driving range into an outdoor concert. Upgraded tickets lead to the Michelob Ultra Brew House between the 8th and 17th greens and The 1834 Club, a shared skybox on the 18th green. December highs sit near 77 degrees. Audience More than 15,000 fans come through the gates during tournament week, and the tournament markets across Naples and Fort Myers.
