I have heard that it is around $100 per night to upgrade, so around $700 for a 7 night cruise. I think that this depends on what Cat you are starting in. We went from a 12 to a 5 (I think) on a 4 night and it was right around $400.
I hope this holds true for 7 night cruises as well. It would save us over $600 to be able to upgrade this time around.
