Hi Courtney!
Thanks for stopping by the Disney Parks Moms Panel. I'm sorry you aren't able to find availability for any royal dining for your girls. The good news is that there are lots of options for dining with Disney Princesses.
Hopefully between
Cinderella's Royal Table,
Akershus Royal Banquet Hall,
1900 Park Fare, and
Trattoria al Forno, you'll find a reservation. Don't give up hope, because I've often found last-minute reservations for even the most popular restaurants.
Here are some of my best tips:
Keep checking back. People's plans change all the time, especially 24 hours in advance when the cancellation policy is in effect.
Be flexible with times and try uncommon meal times.
Try walking up. If I'm in the area, then I'll stop by the podium to see if the restaurants are taking walk-up reservations. I also recommend trying when the restaurant opens or at uncommon meal times like late morning or afternoon.
Even if you don't find a reservation, there are princesses aplenty to meet around Walt Disney World Resort. My favorite spots are
Princess Fairytale Hall in Magic Kingdom Park and Elsa and Anna in the Norway Pavilion in Epcot.
If you have any other questions, please come back and see us real soon. Wishing you the best day ever!
