VIP should print out on your FunPass ON your 10th cruise. If it does not, you need to check with someone.
You simply show the VIP Fun Pass to the Carnival Rep at Embarkation and they will direct you to the VIP Check In.
Also, if you use the free wash and fold...make sure you write "Platinum Free Wash and Fold" on the ticket and on the bag. This will prevent you from being accidently charged for the service....since you use the same bag and laundry tag that everyone else does.
I also never send anything sentimental or delicate....since they are all thrown in a laundry mesh bag and washed with other laundry mesh bags.
