After retiring from the military, James Hewitt embarked on a couple of different business ventures. Shortly after his retirement in 1994, he invested in a driving range in London that eventually closed down. Then, after dipping his toes into the reality TV world in the early aughts, he moved to Marbella, Spain, for a change of scenery. "I wanted to start afresh," the retired cavalry officer told The Telegraph in 2009. "London became like living in a goldfish bowl," he explained. "I've let go of England, but I do wish it all the best. And honestly, it's paradise here: I feel so lucky, and I don't deserve that luck."
In 2009, he opened The Polo House, a restaurant and bar in a posh area called the Golden Mile in Marbella. The Golden Mile is a 5-kilometer strip of coastline with an impeccable view that boasts the best of the best in terms of hotels, restaurants, cafes, beach clubs, and so on. "Having been fortunate enough to have traveled and dined extensively in some of the world's most charming locations, and being someone who loves the arts of fine food, wine, and entertaining, I had carried around the thought of a place like the Polo House for some time," Hewitt shared in an interview with Tout Magazine in 2010. The Polo House was operational for four years until its closure in 2013.
