I would check with your cruise line to see if they have a similar service. I normally cruise with Royal Caribbean and it varies port to port. If you get the airport to cruise transfer they'll send the bag to your stateroom. You drop off your bag at the bus when you board or at the cruise check in desk at the airport and they'll take it all the way to your room. As for post cruise, it varies. In some port they'll offer the service for a fee where they'll send the bag from the ship to your flight and you can pick it up at baggage claim. In Seattle the service is free. I think the most I've seen was $25 for the service. Some ports even have airline check in at the port where you can just check in, check your bag, and get your boarding pass like if you're at the airport.
