Noticed Disney has a 7 day Costa Maya in Sept. 06 that we might be interested in. The least expensive I can find this for is $2220.00. What type of discount would the give me while onboard our Jan. 06 cruise if we wanted to do this one? Thanks! We're debating between this cruise (on the Magic) or a much less expensive one on Carnival Miracle for $1500. We will have a 2 year old. Anyone have a recommendation?
