I just booked a 4 night cruise for Jan 2008. I got the $50 credit for using the Disney Visa and the $25 for booking online through Disney.
What is considered a good credit when you are on a 4 night cruise???
Now transfer your reservation to Dreams unlimited and pick up another Shipboard credit!
From them!! $50.00 I think! Maybe a hundred...?
