Luggage storage or transport service in Miami/Royal Caribbean on debarkation day?

[Bloomin Onion]

We'll be cruising on Oasis of the Seas from Miami this Sunday to next Sunday. Our return flight out of Miami isn't till 10 PM at night on Sunday and we want to spend the day in Miami and Miami Beach sightseeing, All of our luggage is carry on. Does Royal Caribbean offer a service to transport our luggage to the airport so we can pick it up at the airport later? I know they have an offer for luggage storage plus the hop on hop on Miami tour but that is $149 a person. We can buy our own hop on hop off tour tickets for $40 a person and take the metro or Uber to the airport. So we don't need it combined with the tour, plus that package ends too early at 3 PM and we want to do more sightseeing. 

 

Are there private companies around Bayside Marketplace that do luggage storage that any of y'all have experiences with that are reliable?

Luggage Lounge in South Beach will hold your bags for a fee while you explore.

You know of anything closer to Bayside Marketplace? It would be more convenient for us to start and end the tour at Bayside vs in Miami Beach so we can head straight to the airport at the end.

From South Beach you can take the Miami Airport Flyer bus to MIA for about $4 each.  Uber and a taxi are also options from South Beach.
