This is practically a must do tourist thing to do. This tour gives you a great tour of Star Island, Millionaires Row, South Beach, etc. Once, you get out on the open water they let it rip at high speed (nothing like it). The tour leaves often (every 90 mins) and makes it easy to catch or work into your schedule if your doing other things at Bayside market place. While waiting for the tour I had banana/strawberry fruit smoothie, perfect for a hot summer day.
I would recommend this tour just for the great views of the Miami skyline. A little pricey but, on par for these kind of tours.
