Hannah & Bill -
You might want to try a shorter cruise. We did that last spring. Went on the Sovereign of the Seas out of Port Canaveral on a four day cruise. Booked two inside cabins next to each other and got the 3rd & 4th person rate on the second cabin. My husband and myself were in one and the kids were in the other. The advantage to this was 2 bathrooms! We booked early and got a fantastic price (booked in October 2002 for April 2003). I beleive it was about $1500 for the six of us for the cruise. Good luck and happy cruising!
