Unless you live in Southwest Dade, the Tropical Park Tennis Center isn't exactly convenient — but therein lies its unique appeal. You can actually nab a court without lurking for hours or booking days or weeks in advance. Sure, reservations are recommended during the peak hours of 6 to 9 p.m. (courts are open till 10 Monday through Thursday and 8:15 on weekends), but stop by on a weekday afternoon and you and your partner might just find yourselves playing in solitude. The dozen courts are well manicured, with few if any of the disorienting cracks that mar most public tennis courts. And if you find yourself in a queue for a court, there's almost always room to practice your stroke on one of eight nearby racquetball courts. Plus the price isn't bad: $3 per person per hour before 6 p.m. and $4 thereafter.
