On one of our last b2b cruises, those of us that were on the next sailing were waiting patiently in the lounge as required before disembarking and re-boarding the ship. We were unable to do this because a couple of people decided they wanted to wait on ship as long as they possibly could. At this point ship officers asked those in the lounge if we were on the next sailing. Once they got to this couple - and found out they weren't they were told at that point they "had to leave.' Yes, they were the last people off the ship - but also left the rest of us that were waiting to start our next week of vacation at a stand still because a couple of people decided it would be better to wait on the ship as to make other plans for when their cruise was over.
