Flight out of MIA at 3:00 PM, any idea on how to kill four or five hours after our cruise? Five adults, what to do with luggage is a consideration. Would we have time to cab/Uber to the airport and rent a vehicle? Last time we came back to Miami we had a larger group. Hired a service to pick us up, took us to Bayside Marketplace and held our luggage, then came back for us and took us to the airport. That was ok but looking for other ideas. Any thoughts?
