You don't say which cruise you are going on. Some have a larger difference. It depends on how many rooms in that category had been sold by the date you booked your original room. If it is a popular cruise that has sold well, it is very possible that there is a larger difference in price between stateroom categories.
Do you currently have a room assignment? If your category is sold out, you might want to see if you could switch to a guarantee (rather than an assigned stateroom) and take your chances at maybe getting an upgrade that way (although you would lose your choice of stateroom, if you had one chosen). However, I do believe that March 31 is Easter, and with holiday sailings things tend to cost a lot more, including differences in category.
It depends on how many cabins are available in each category and how many are on the ship total.
Also, since you are already booked, the price to upgrade may be less than what you are seeing for a new booking on the web site.
mom4fun said:I booked our cruise back in August, a 7a. I decided it might be nice to upgrade a little. The price to go up 1 level, a 6b, is almost $400.00 more. Does that make sense? It shows on most cruises to go up about $20-30.
Are you saying that your price to upgrade is $400 but in other sale dates the difference between those levels is $20-30?
My guess is that your upgrade price is based in the price of your 7a on the day you booked (compared to today's price for the 6b). Other "upgrade" costs would be based solely on today's pricing of both cabins? Someone please correct me if I am wrong!
