I'm looking at booking our first transatlantic cruise while onboard Brilliance this October for next November 6, 2014 on the Serenade OTS from Barcelona to New Orleans. It's a 16 day cruise!! (The longer, the better in MY eyes) We'll be booking a JS
. I've found a savings certificate for this cruise that expires this coming September on the C&A membership page. Can this be used afterinitial booking, when I call to make a payment, even with our Diamond discount AT booking, or does one negate the other? Never had the chance to use one before-any way to reduce the costs is a "good thing", since we still have to pay for a LONG airline flight too.
