Included in our Raddison documents was a service that picks up your luggage at home and promises to have it in your hotel or state room when you arrive. Same service guaranteed for the trip home.
I assume they use an overnight shipping service. Benefits are no security hassles and no restrictions to size and weight, after you pay. You can then travel very, very light.
We were driving so I discarded the brochure. Wish I had kept it.
