I'm sure this has been answered, but I haven't found it yet w/ the search results. If we rebook a 3 day 'dummy' date while onboard we get 10% discount and $100 OBC.... If the cruise we move to is a 7 day, I know we still get the 10%... will the OBC automatically jump to $200? Also, in this case we might actually move the booking forward to a 2013 Med. cruise... any problem moving forward as long as there's availability?
