Looking at the ship deployment it will either be the Sapphire or the Coral doing the 2026 WC from Ft. Lauderdale. I personally think it may be the Sapphire since it is doing the 14 day Circle Caribbean Holiday December cruise ending back in Ft. Lauderdale on January 5, 2026, which is usually around the date the WC begins from Ft. Lauderdale.
It's a mystery on what the Coral will be doing. It currently doesn't have anything scheduled after it arrives in Ft. Lauderdale on November 13th. Maybe going into dry dock or maybe South America for the 2025/2026 season. It also could be that it will be doing an extended world cruises itinerary, which visits different ports and is longer than the traditional 111 day world cruise that Princess normally does. I guess we will find out in due time.
