Using a shuttle to Miami port is a great way to get your cruise started. It offers you a stress free way of traveling to your destination, without having to worry about Miami traffic. Miami is a very large city, and as such it has lots of traffic hovering around it. It’s best to let people who drive in it daily get behind the wheel so that you don’t end up with your car trapped in traffic instead of having your butt in a lawn chair sipping champagne. Personally, I like the second option a whole lot more. Not a big fan of traffic.
