I've looked at the different agreements that
DCL has in place. with the exception of PC which is still being negotiated they all specify a ship size. Galvestons specifically says 2700 passenger minumum vessel, Miamis says 3500 minimum. That's in addition to number of sailings. Miami is also in talks with Disney on first right for a new terminal near terminal j or a suitable space on the other side if that area doesnt work out for development. It's in Miamis agreement that the ships would be doing 4/5s which is 2x a week. The gradual increase also accounts for higher traffic or movements. 100,000 passenger movements is 28 sailings. 14 weeks. Which is about what they are doing now.
360000 movements would be 52 sailings., which coincides with the new ships arrivals. Based on 3500 passenger count. Basically it's the same thing, just worded differently. Miamis also specifically says 2 large ships which means that the Magic class may make an appearance there form time to time, the 5 Dream and Tritons are the candidates for Miami homeporting. Miami hasnt decided yet on shoreside or waterside LNG but there going to do 1 of the 2 by 2022, and that was as of Jan of this year.
