We flew into Miami the day before and stayed in a timeshare unit by using our Wyndham(Fairfield) points.
None of the rental car companies allow you to drop off a rental at or near the pier, so we returned it to the airport and took a 24-dollar cab ride to the Port of Miami.
Azamara is using the other side of the complex away from the usual piers. It's the first right after going over the causeway.
