Actually even if the Wonder doesn't go to the West Coast they'll have 3 if not 4 ports to sail out of, Port Canaveral, Miami, Galveston, and New Orleans. (the latter where the Wonder is intended to go anyway for the winter season). Also other cruise lines are bring more than 2 ships back to U.S. Waters, the CDC has no real say in how many ships can be here, just that they meet the Safety protocols and also pass the Color Coded quarantine status (red/green) once they do return here, which will likely mean each ship will have to quarantine off shore for 14 days with out a positive CoVid-19 test before they can enter any U.S. port. Most likely to alleviate congestion at Port Canaveral (which would be the logical choice for them to set up and operate the "test" cruises out of) and to qualify for certification under the Framework for Conditional Sailing Certificate (CSC) they'll stagger the ships arriving in U.S. waters so that they can run each ship through the process. The Wonder looks like it might be the first ship back, quarantine then start the (CSC) process, with the Fantasy arriving shortly after, then either the Magic or Dream will follow, we'll know more once we see the next ship depart Europe.
I read the Framework document and didn't see anywhere where each port has to test a ship before it can be given it's CSC to begin sailings, just that the ship has the capability to handle the protocols and procedures regarding the virus testing, and facilities necessary for any problems on board. I am pretty sure they will certify a ship at a single port to work out of any US port if they get the certification, especially if they're constantly checking on them. They're just going to require the cruise lines (ALL OF THEM) to guarantee that they will facilitate the handling of any guests or crews that get sick or test positive while on board and make arrangements if they need to offload them at a port for medical treatment or quarantining. The logistical nightmare of certifying every single ship out of every port it goes into would take MONTHS to accomplish and that would require dozens of "test" voyages for the lines and astronomical costs to the cruise lines. I am pretty sure from what I read that the certification can take place with one voyage, it that ship passes it can then make arrangements for revenue sailings.
While I see the logic behind the idea of using WDW resorts for quarantine, I don't think they will do so. Largely because of the existing return-to-work contracts that were negotiated and the impact to CMs who would work at those resorts. That's a guaranteed risk of exposure, and those contracts are all about limiting even potential risk of exposure.
I think they will drag out the cancellations, as usual, since they like to hold on to the money as long as possible.
