Donna: go to carnival.com, then go to Book now, sign in, look under gifts and services and then specialty items. it states the coupon is god for 3 5x7 or 2 6x9 for $15, but it looks like it might be good for $15 off regardless of what type photos you get. you will also find many other items and gifts that may be useful to you. just explore it all. have fun.
