I had two couples who were suppose to be on the first sailing after dry dock. But three weeks before their cruise, Carnival decided that in response to the huge problems encountered by the Triumph, they were going to keep it in dry dock for an extra month to add new redundant back-up power supplies, among some other essential items to try and prevent those problems from occurring again. Needless to say, my clients were extremely irritated that 3 weeks before their cruise, they had to redo all their plans (time off from work, airline reservations, hotel reservations, excursions, etc.). Carnival did provide them a 25% reduction on their next cruise as well as refunding them the airline change fees. But this was what Carnival said was a one-time itinerary and included stops they wanted. So now they are going in the Fall instead of the Spring and they're getting one less day plus missing a port they really wanted.
I've always been one who does not like nor suggest the first cruise on a new ship or the first cruise out of dry dock because of the very reasons the Sunshine has encountered. It just takes a couple of weeks to iron out all the problems, get the staff to become a cohesive group, and insure a care-free cruise. Plus, it gives a bumper period just in case the ship is delayed in getting into service.
