I did this two weeks ago…went from the Symphony in Miami to the Allure at Port Everglades. I let Customer Service know the second day on the Symph. Followed up again on the fifth day. I was given a special number luggage tag, disembarked at a specific time, got luggage, went through customs and went outside. Asked where the RC busses were and walked over there. Make sure you get on the port to port bus. We stopped at the Ft L airport first, then we went to the port. All in all it was easy.
