I'm booked on a 7 day New England/Canada cruise onboard Carnival's Victory departing Sept 11, 2004 as a single (1) costing $1,798.00. When I called Carnival to ask how much it would be to add a person ( which would be a total of 2 in the cabin) their customer service rep said an additional $899.00 when I asked why she said because I already paid my full fare and additional means 3rd or 4th person so the second person must pay the $899.00 even though if we had booked together from the start the total for 2 of us would have been what I paid alone. This just doesn't seem fare to me. If someone goes with me now the cruise lines end up making triple on the fare. Has anyone else ever run into this problem?
