I don't know if this is a silly comment, but can you guesstimate where the Treasure will be based on the announced sailings for the other ships? It would appear, based on the website (filtering for Nov/Dec 2024 and each ship individually):
Wish: Port Canaveral/Bahamas
Fantasy: Port Canaveral/Bahamas
Dream: Fort Lauderdale/Bahamas & Western Caribbean
Wonder: Auckland-Melbourne-Sydney/Sea Cruise
Magic: Galveston-San Juan/Bahamas-Western Caribbean-Southern Caribbean
Does this leave the Eastern Caribbean ports open? Or aren't there generally West Coast ports served out of San Diego?
