It's been reported that Celebrity has moved up Apex's dry-dock to happen this Fall instead of next Spring. That seems to support the idea that they're having a propulsion or stabilizer problem, combined with so many itineraries being changed in similar fashion (longer sailing times port-to-port) and shorter times in port. Our itinerary for a June 15, 2024 sailing has already been changed twice, each time shortening port stays by an hour here and an hour there.
