On a budget, weigh it — Jet Ski / Watersports on Biscayne Bay isn't cheap for what it is.
~$100–150/hour + fees
A genuine adrenaline highlight — open throttle across the bay with the skyline and Star Island mansions around you, and the breeze is welcome in the heat. The catch: it's pricey by the hour, operators add fuel/insurance fees, and choppy water or a guided 'follow-the-leader' format can dampen the thrill.
