This more than anything I have read on CC has prevented me from booking on MSC. We tend to book far in advance, and have cruises booked into Sept 2021; I have never had a reason to believe that Disney, RCL, NCL or Carnival would look to change the deal after the booking is made and the deposit is paid. And for all lines we've cruised we have found on-ship guest services to be very helpful, and always polite even when they couldn't help us.
I do see that many folks are reporting that MSC honored YC booking perks even after they made changes to their packages, so that gives me hope that MSC is adjusting the way they roll out changes. It would be nice to have a definitive statement from MSC that the deal we booked is the deal we'll get. That's my take anyway.
