As a general rule all passengers are supposed to be off the ship by 10 AM.
That time could be different if the ship gets in late due to fog, etc.
In addition to the above information you might want to know that Princess wants everybody out of their cabins by 8:30 AM. This is the trade off for having the cabins ready for you when you board.
