In this time of limited luggage weights, and airline luggage charges, it would be wonderful if luggage could be sent ahead by the Postal service to the cruise peir. There it would await our arrival, and be placed in our cabins.
At cruise end, have it shipped home the same way. Passengers would not have to deal with more than carry-on luggage at the airport.
The postal service offers insurance, and delivery confirmation as well.
Just a thought.
