Hello Kim,
Oh my goodness what a dilemma of a question for me to answer; because I love both!!
Cinderella's Royal Table and Princess Storybook Dining at
Akershus Royal Banquet Hall are equally delightful dining experiences for not only your dear little 6 year old, but also for every member of your party. I can assure you both venues have delicious menu options and of course provide Guests with the opportunity to meet and greet with lots of lovely Disney Princesses.
However, the greatest and in my opinion most magical and exciting thing that
Cinderella's Royal Table does have over
Princess Storybook Dining is that Guests actually get to dine
inside the majesty of Cinderella Castle!
I'm sure where ever you choose you'll make some magical memories that will last a lifetime.
If I can help sprinkle some extra pixie dust on your upcoming trip to Walt Disney World Resort please pop back to ask me another question.
Have a great Disney day.
~ Jane
