I'm sort of dum(b) and confused. Are you saying to book when the dates are first available and to rebook onboard? So, if the price goes up by the time you are onboard you still get the, one assumes, better price from before? (I'm confusing myself just writing that.)
Ok, so let's say in Oct the dates are released and you book cabin XYZ for $3000. Then you sail and rebook it in March. In March the price for your same room is now $4000. Do they give you the 10% onboard credit off of $3000? Or do you now have to pay the $4000 less the 10%?
