If you cruise just once with Canival you will be assigned a past guest number. You can get this number by looking at the lable of your Currents magazine or by calling Carnival. The Currrents contains some coupons for discounts on some select cruises. The only other benifit is the past guest party. If you are a past guest and have checked the box on your docs (your Ta should have asked your for past guest number) you will receive an invitation in your room for the party. You must prersent your invitation in order to get into the party. They will hav free drinks and canapes, the CD will give a talk and you will be introduced to the Captain. There are no added benifits or considerations for the number of cruises you have been on.
