Well there's a chance you could get upgraded, but don't set your heart on it. It all depends on how sold-out the resort is, but Sept 9th is traditionally a pretty quiet time - unless the free dining offer has had a real impact anyway.
I would suggest being straight with them in your fax (send it 5 days out) and say that you tried to book a RR in the first place but the system kept saying none were available for the dining plan offer, and that you've been re-checking ever since in case anything came up. Ask them if there's any chance that any Royal Rooms have become available in the meantime, and mention about your daughter having fallen in love with them from the photos and how it would really make the vacation extra special for her. Offer to pay any difference in price (although it's unlikely they will actually charge you). You can ask again when you arrive at the front desk.
Good luck, hope it works out for you.

Thank you so, so much. I faxed the letter below today. Does it sound okay? Today is 7 days out and I would not have access to a fax this weekend plus I've read not to send on a Monday and feared Tuesday would be too late. I hope that is okay. Thank you so much.
Thank you again!

Hello!
My family is getting ready to check in for our second trip to Disney World! This is a very exciting time for us because our daughter will be turning five and she will be old enough to remember and enjoy this trip!
We have made some reservation requests which are noted in our reservation. If our below request is unavailable, we would love to keep the requests that are noted there.
Our daughter, Addison, is a true princess at heart. From the time she was old enough to recognize them, she has been in love with the Disney princesses. Tiana is her favorite. During our last stay, we stayed at Pop Century and loved it! We chose to upgrade to your resort at Port Orleans in hopes of a Royal Guest Room. We have called religiously and not been able to upgrade to one of these rooms due to they are all full under the free dining promotion by trying to modify online or by phone. We do not want to lose that promotion. We have noticed there are some Royal Guest Rooms still available for booking, just not under the free dining. We would love it if we could possibly upgrade to one of these beautiful rooms. Our Addison is convinced she is going to be staying in a princess room and it would mean the world to this mother to make that dream of hers come true, especially for her birthday.
If could accommodate this request, it would mean the world to us for our daughter and truly make her birthday the best yet. She sings about going to her Royal Room.
Thank you so much for your consideration,
