It worked great for us. We had a suite on the Inspiration. Just came back on July 4, 09. We ended up with six separate discounts each a and a hundred dollars on board credit each. The cruise ended costing us what an outside cabin did years ago on the same ship and five days cruise instead of four days. It was well worth working the discounts. but it did take some time doing the discounts and finding them.
