So, back in October, I submitted the form for my upcoming cruise, and it resulted in them sending me a cancellation notice for "lack of deposit" even though I had it all squared away, in theory. There was a slight difference between the deposit I paid originally and the deposit necessary for the new rate code. Fortunately, I saw the email right away and was able to call and get it sorted out but I almost missed out on the stateroom I wanted. I'll be careful of that in the future.
