Hi Andre,
Bem-vindo ao planDisney! It is great to see you here!
I did a little research to help you get on your way with your plans. Several major rental car companies operate out of Miami International Airport and have drop-off locations close to
Port Everglades, where Disney Dream departs, and offer shuttle transportation to the terminal. I encourage you to search "rental car pick up Miami airport drop off Port Everglades" and you should be able to find a car rental option that works for you.
Andre, if you simply need transportation from the Miami airport to Port Everglades, you could consider an app-based ride-share service. The ride from the airport to the port is about 30 miles. It might be the most cost-effective and easiest option for you since they will drop you off close to the terminal entrance.
Disney Cruise Line values making all Guests feel welcome by offering
Special Services for Guests needing assistance. You can
contact Disney Cruise Line and discuss your specific needs with a Cast Member. A limited number of wheelchairs are available at the cruise terminal for Guests needing assistance making their way to the entrance, so be sure to keep an eye out for these when you arrive.
I hope this information is helpful, Andre. Please let us know if you have other questions; we are here to help!
Wishing you many magical memories,
Shannon
