This mangrove-lined inlet provides ample space for personal watercraft fans to get the rush associated with this noisome pastime. What's that you say? You don't have your own personal personal watercraft? Well isn't this convenient? Tony's Jet Ski Rentals is located just west of the marine stadium. For $45 you can splash around for a half-hour ($70 per hour). For the same price, you and your honey can mount a tandem unit. If you can afford to pony up a few more bucks, you and two honeys can ride a three-seater. To reach the marine stadium, take the Rickenbacker Causeway toward Key Biscayne and look to your left. If you're in the market to rent, follow the signs to Tony's.
