Heigh-Ho Aaron,
Thank you for bringing your question to planDisney and I hope I can help with your curiouser and curiouser inquiry. Guests, with children under the age of 3, do need to include all ages in their Advanced Dining Reservation headcount. Walt Disney World restaurants need to operate within code and capacity limits so they kindly ask every Guest, no matter their age, to be included in their number request for
dining reservations.
Aaron, between now and up to 24-hours prior to your reservations at
Cinderella's Royal Table, I recommend making every attempt to modify your reservation. You can do so daily through your My Disney Experience account and trying to modify your current reservation or trying for a new reservation, calling (407) WDW-DINE and speaking to a Cast Member or by using the Chat With Us feature through your My Disney Experience mobile app. Your party will need larger than a 4-top table and I can't guarantee they will be able to seat you. Stay vigilant and keep checking, reservation availability changes daily and with a little bit of Faith, Trust and Pixie Dust and hopefully before the clock strikes 12, your fairytale dining wish will come true.
If I can be of any further assistance feel free to ask and may your upcoming stay be filled with many magical and memorable moments.
Have a Practically Perfect Day,
Amy M.
