We just booked under the military rate. no special that I know of but my paper work said TBA...guarantee
any way we feel lucky to be able to book military rate because the savings are really really great. More money to spend on the ship.
We have always booked a oceanview and so I figure it cant be bad.
One time we booked military rate inside cabin, a week before the cruise they posted a price for an ocean view which was only 10 dollars more then what we paid. Jumped right on that, call carnival paid the extra 20 dollars (for 2 people) and got a great room.
