Lobster was served on the final formal night. I believe disembarkation for people taking off their own luggage started at around 7:30, and 8:30 for the rest of us (depending on your luggage tag number). But if you don't want to take off your own luggage but want to get off early, its easy. Luggage tags were made available at 5:00 the day before, in 3 locations. You can just grab what you wanted. If you go right at 5:00 you can get one of the lowest numbers and get off at close to 8:30.
