Ten Har-Tru courts immaculately maintained in compliance with Coral Gables zoning laws. A view of the Al Capone suite overhead. In the background a stand of pine trees and the expansive green lawn of a championship golf course. The Biltmore Tennis Center is a true racket paradise. Hacks and professionals comfortably coexist on crack-free courts, lobbing tennis balls over nets that never sag. Lights illuminate night play. Racket rental is available, as are private lessons. The center, which caters to hotel guests, is open to the public and is rarely overcrowded, even during the tennis prime time of Sunday morning. If you live in Coral Gables, the cost is a mere two dollars per hour. Those of us who can't afford a million-dollar home in the City Beautiful pay four dollars per hour, still acceptable for such fine facilities. Hours are 8:00 a.m. to 10:00 p.m. weekdays, 8:00 a.m. to 8:00 p.m. weekends.
