Storing bags post cruise - Miami Port area

My granddaughter is coming back to Miami from a cruise on Mar. 17th. She has has a motel reservation near the Miami airport. She'd like to take in some beach time before taxiing over to the motel, but doesn't know where to store her bags, if she possibly can. I'm driving over to take her and my great granddaughter out for a late lunch and a visit. Anyone have suggestions as to where she could store their luggage to free them for awhile?

If you're going to be taking them to the beach then they could keep their luggage in your car. If you're not taking them to the beach and they want to go there directly off the ship...I can't think of a single place where they could store their luggage. I hope someone else on here can help you.:D

Hope you have a nice lunch with your family!:D

Most hotels will hold them for you.

Reportedly there is bag storage at a luggage store inside the Bayside Market; she could store them there until you and your car arrive and save herself an extra trip to her MIA airport area hotel.

Thanks everyone for your info If anyone else has some thoughts, I'd appreciate hearing them.
