If you have a few hours to spare before your boarding window at PortMiami in 2026, the best and most convenient option is to visit Bayside Marketplace. This waterfront open-air mall is just a 5-to-10-minute taxi or shuttle ride from the cruise terminals and offers a wide array of shops, restaurants, and live music. It is a great place to grab a "last meal on land" or pick up any forgotten essentials like sunscreen or hats. For a more relaxed experience, you can walk through the adjacent Bayfront Park, which offers beautiful views of Biscayne Bay and the arriving cruise ships. If you have 3 or 4 hours, taking a 90-minute "Millionaire’s Row" boat tour from Bayside is a popular choice to see the celebrity homes on Star Island. For those with children, the Phillip and Patricia Frost Museum of Science, located just across the bridge, features a world-class planetarium and aquarium. Most cruise passengers choose to stay in this "Downtown/Bayside" corridor because it is close enough to the port that you don't have to worry about Miami’s notorious traffic delays.
