Parking at the Port Of Miami is the safest way to go. Current pricing is twenty two dollars a day. Unfortunately there really aren’t any safe prices to leave your vehicle in the City Of Miami that will save you any money. I have been a member of Cruise Critic since 2002 and have read many posts regarding off site parking in Miami. Posters have complained of damaged vehicles, stolen items, and in one specific incident a homeless male broke into a parked vehicle and was found to be sleeping in it.
