I just wanted to write a comment about my recent cruise with Royal Caribbean. They offer a service called Luggage Valet where you get your airline boarding pass and luggage tags delivered to your cabin the night before you return back to the port. The morning we disembarked we were one of the first off of the ship as we didn't have our luggage with us, it was great! We disembarked into Fort Lauderdale and were able to enjoy the beach with our kids before we had to go to the airport to fly back home.
The program was only $20 per person and was well worth it in my opinion not to have to lug around our bags for the day with the kids. I recommend this service to all who haven't tried it!
