If you said adjoining, all that means is rooms near each other. If you want rooms with the inside door you need to ask for connecting. To Disney they are very different things.
I really take issue with some people from Disney promising things over the phone they have no business promising. They have no way of knowing what type of room or room set up you will get at check in--your room isn't even pre-assigned until a few days ahead of your vacation! Disney doesn't keep track of rooms that connect vs adjoin, as neither is a category that we can book.
Odds are good you will get what you request for, but I've been denied by the Disney request gods more than once. So it does happen! Heck twice I've not even gotten the type of room I have booked! I've been downgraded.
