Welcome to planDisney Matthew!
I am sorry you still have had no luck in locating the robe you would like to purchase for your wife. You have some time until you set sail, so hopefully the item you would like to purchase will become available on through
Onboard Gifts for your sailing.
If you are unable to prepurchase the robes, let's think of a few options! Start with looking online at other robes that you can purchase and bring with you. I am guessing she would enjoy a gift from you that you brought all the way from home!
Another option is to check with the gift shops or at the
Senses Spa & Salon once onboard. They may have some robes for sale, but I cannot guarantee what they will have to offer.
My final suggestion will be to
send an email to Disney Cruise. Under "Subject" select "Merchandise Guest Services." Responses are taking a bit longer than usual, but maybe they will have some additional help for you.
I hope you find the perfect gift to give to your wife to add even more magic to your Disney Cruise! Bon Voyage!
