We cruised in March, and that was the first I had heard of the veterans discount as well. Actually, our TA had asked me if either my husband or myself once served in the Military. At the time we booked, I do believe that we had an option of booking up to 3 cabins under this military discount (my memory may be off a bit on this), since we only booked one cabin I am not remembering how additional cabins could have come into play.
Anyhow, I recall we saved approx. $135.00 pp on a balcony cabin onboard the Valor. I did not inquire about the savings for other cabins, as we have become very spoiled with having our own balcony!
I do know however, that we did have some friends decide to join us on the cruise....and they were on the same deck as us, 10 cabins down with an inside cabin, and paid MORE than us with our military disc.
For as often as you cruise Dave, you had best check into this new veteran offer onboard Carnival!!
