I find that having the tips on my sail and sign card a real convience. But, because they are put on your card no matter what the service I would rather call them a service change . I know Carnival will never call them that just to make the price of the Cruise seem lower than it really is. It just a big game. I am sure no one is fooled . I would prefer that the cruise was priced like an all inclusive resort. All fees and charges up front. No need for any games and illusions.
