The best transportation options for getting around Miami Beach are walking or a bike. With either option you don’t have to worry about finding a parking place which is a huge challenge in South Beach. Other reasons include taking in the sites and getting a great tan and workout on the way to your destination. Deco Bikes has set up bike stations throughout Miami Beach and all you have to do is put your credit card in the machine and you can rent a bike for a few hours or a day. After you are done you can leave your rent a bike at any Deco Bike station close to your final destination.
Other options to consider is a skateboard or roller blades but they could risk you spending your vacation in a cast so maybe thats not the best idea.
You could rent a car but parking is not easy and can be quite expensive in South Beach so its not really worth it unless you are staying outside of the South Beach area or plan to visit other areas of Miami. All South Beach hotels have valets they charge around $40 dollars a day to park your car or you can park at one of the many parking garages located thoughout Miami Beach. Or if you want to see the city without a rental car you could take a city tour there are many great tour options that you can take right from South Beach to all the historical areas of Miami.
