We were on Carnival Freedom - did complete the paperwork for their "protection program" but that seems mostly for when the appraisal of an item doesn't match the vendors claim. We have contracted Carnival PPI but have not heard back directly from them. DI is still holding the ring because my wife told them she doesn't want it any more - because the have her so mad. They have offered her a $100 gift certificate but she is not interested in every buying from DI again (right now) ... and Carnival is on the bubble for her as well. The kicker for Carny is this was the only "shopping" port on the itinerary - so the only port where the Destination Shopper really had anything to do..
We have contacted the credit card company - we'll see what they can do.
