I recieved a gift ... all expenses paid cruise, gratuities included. After receiving my docs, I called Carnival asking if "coupons" (which I have read somewhere, would be provided for me to place in the tip envelopes) for prepaid tips were available. Their answer was no. What should I do? This is my first cruise, I want those who deserve tips to receive them, but wonder if they will ever see the prepaid tips. Do the service people know in advance who has prepaid? Thanks in advance for your advice.
