Hi Lisa,
Dining at
Cinderella's Royal Table is truly an enchanting experience. Due to the popularity of this restaurant, reservations should be made 180 days in advance. You should start trying at 6:00am online or 7:00am over the phone by calling 407-WDW-DINE. Our little girls absolutely love eating inside the castle with the Princesses.
To make it extra special, we take them to
Bibbidi Bobbidi Boutique first. They are transformed into Princesses themselves, complete with shimmering makeup, and tiara's in their pixie-dusted hair. Your little girls would likely love the Boutique.
If you are unable to secure reservations at Cinderella's Royal Table, you can also try the Princess Storybook Dining at
Akershus Royal Banquet Hall in Norway (Epcot). While this isn't located inside Cinderella's castle, it is still a magical experience.
Hope this helps and please let me know if you need further assistance planning your first Disney vacation,
Kaylene
