We love our platinum perks. My daughters love the free arcade tokens. My husband and I appreciate the free laundry. All of us enjoy the priority tender tickets. And at the end of the cruise we love getting off the ship at our leisure, because no matter when we get off we know our VIP luggage will be cleared and ready and waiting for us. The special line at the purser's desk has come in handy several times but I always feel guilty using it when others have been waiting so much longer for someone.
The complete list I think is on the Carnival site. We think the perks are worth it. It's nice to get the special treatment....Oh and before I forget, my youngest daughter is a chocaholic and she adores the chocolate coated strawberries that arrive in place of the free canapes.
