Disney cruises are great. I've never heard of any discount codes for them, but the best way to get a good rate is to book as far in advance as possible. 2007 rates should be released in August. Another option is to book through a
travel agent that reserves large blocks of rooms. Once you go on one
Disney cruise, you can rebook on board. When you rebook on board for a 7 day, you get 10% off and a $200 onboard credit. Our first cruise was a 3 day. We loved it so much we rebooked for December 06 and got a great rate plus the credit. Check out the
DCL discussion board for more info.
