We a are flying into Miami the day before our Royal Caribbean cruise. We were looking into using a car rental site like Turo (think Airbnb for cars). Ideally, what we’d like to do is drive it to the cruise port pay, drop the car off and have the owner pick the car up later that day. So use short term parking. I know this is super complicated, the reason for this is is boarding day is the day of the Miami marathon and we’re anticipating surge pricing on the morning of boarding plus it would be great to have a car to tool around for the day before we arrive. Any advice of info of whether this is possible or not?
