I've read through a few past threads discussing dummy dates, but I'm still not sure I understand one aspect of the "system." Let's say I book a cruise for March 2014 while I'm onboard the Fantasy in March 2013. Then we decide two or three months later that we want to go in the summer of 2014 instead. I understand that we'll keep the OBC and the 10% off (and will have to pay any difference in deposit), but will we get the pricing that was in effect when we booked onboard or the pricing that's in effect on the date that we make the change? Thanks in advance for any insight!
