When we have early flights, we drag our luggage off ourselves, early. It makes for a much faster disembarkation, and a shorter wait in the customs line.
However, we have not booked early flights since 2017, and ALWAYS (now) stay a day after the cruise in a hotel.
If you dont book close-in flights, this is the best piece of advice I can give you, because, it allows you to pack your bags however to make whatever fit, and not be concerned about keeping the weight below the Airline Maximum. You can re-pack in the hotel, instead of wasting precious cruise time to weigh your bags out!
