Hi Mike!
Thank you for visiting the Moms Panel!
I think if your daughters love everything about princesses, they will love to dine at both locations.
The common theme is meeting some Disney princesses - at both locations the princesses will visit with your family at your table, and pose for photographs and sign autographs - I am sure your own little princesses would love to do this twice!, and the chances are they will meet some different princesses each time.
Cinderella's Royal Table is located inside Cinderella Castle at the Magic Kingdom Park. This is a lovely and unique setting, which will only add to the excitement of the occasion. Cinderella herself will greet you in the lobby for a photo opportunity, before you are shown to the dining room and seated at your table.
Akershus Royal Banquet Hall is located in the Norway Pavilion at Epcot and resembles a 14th century Norwegian castle. It is worth noting that it is much easier to secure a reservation here.
Advance dining reservations can be made for both character meals, either
online or by calling (407) 939 3463. As Cinderella's Royal Table is very popular, it is recommended you make your reservations at your earliest opportunity, up to 180 days in advance.
You can also meet several princesses at the Town Square Theater in the Magic Kingdom Park, where they are available for character meet & greets.
If you have any other questions, please come back and ask me - I would be happy to help you plan you magical vacation!
