I have a category 6 on hold for the 7 day Halloween cruise and the 10 day Christmas cruise in 2006. I was shocked to find out that the cost of the 10 day was DOUBLE the cost of the 7 day. I've never been on the ship before (we're going in July 2005 for the first time)...is this cost difference normal? Is it worth it? The price is 6800.00 for a familly of 4 (2 adults, 2 children) WITH airfare, transfers, and insurance for the Halloween cruise...and 12,995.00 for the Christmas cruise. Advice from those of you who have cruised either would be greatly appreciated!!!
