I take a different view here. Since the OP seems to have a lot of issues with MSC and false information, you would expect that they would question this. Also, they say they are seasoned cruisers. How often do you dock at 6 am and not get off the ship for 2 hours. I would have questioned it immediately. I would have also asked my butler and listened to the ships announcements and not relied on the YC staff to get me off.
