Make sure you will need a car. General rental looks cheap, but don’t forget you will have to pay for hotel and street parking, and for gas (in addition to extra insurance). Also, you may be worried with safety, driving directions and traffic. Alternative transportation such as Uber or renting a Citibike may be good choices. Please check Citibike rental locations on their website (http://citibikemiami.com). Make sure you respect city bike rules and pay attention to pedestrian areas and stay on bike lanes (when available).
