We haven't been in Cabin 6393 and you may not find anyone who has had this exact cabin. It seems to be an "unusual" cabin, as there are only three 1a's on the Upper Deck.
You may already know this from looking at the Carnival site. It's amidship (which is good if you're prone to sea sickness) and near the elevator and stairs. It's below other passenger cabins, and above a common area.
I hope someone else can give you more info about 1a's.
I'm sorry to hear of the loss of your DW. My thoughts are with you.
I hope you enjoy your cruise,

Can't tell you anything about your cabin #, but I can tell you that the Valor is an awesome ship ! You'll have great service, and alot of shows to watch, good food to eat, no matter where you eat The wife and I sailed on her in May, and we both hated to end the cruise. Wish we could've done a back-to-back cruise on her. May you have sunny skies and smooth seas .
