Cas, They are probably offering the "Endless Summer" promotion that has upgrades this coming week. It is applicable on new bookings only and has blackout dates, and a ton of restrictions. They are usually a little flexible on the new booking part for people this far out of penalty.
Did you have a PVP, or did you call General Reservations?
What is a PVP??
Here is what I do;
Well First I call 1-800- carnival (general) and ask the person who answer about it mostly the same when I did the booking, then after he said he cannot give me the upgrade I call the person who really make my booking and he told me the same.
the way I see it I am so far from my cruise that I am considering to cancel it and re-book it with a travel agent because they are giving me better prices than carnival
What really escapes my mind is they are giving better offers to new cruisers than past guest...
