eyeblazy-It is a good idea if your travel agent will give to you a statement in writing for you to present the purser-just in case the cruiseline claims lack of knowledge. Our experience with onboard crdits has always been good. It usually will appear on your shipboard account a few days into the cruise. The Purser, if advised of it early in the cruise, will invariably look into it and advise you accordingly. We have always gotten our credits with relatively few problems covering over 50 years of cruising! Any documentation you carry with you regarding this is invaluable should a problem arise.
