I might agree that the changes themselves are fairly minor, what really bothers me is the retroactive way it is being implemented. Going forward, if I book another future cruise, how can I know that what I will get is what I thought I was getting when I booked? How can I be sure Princess will not institute another "upgrade", say to give Plus Package people two "free" shows in the theater at night, and additional ones are now $20? Can anybody be sure such a change, or something else, won't suddenly, with no warning, be imposed? My trust in Princess is way down.
