Heigh-Ho Theresa,
Thank you for bringing your question to planDisney, I hope I can help with your dining conundrum. Guests with children under the age of 3 need to be included in the
Advanced Dining Reservation headcount. Walt Disney World restaurants need to operate within code and capacity limits and kindly ask every Guest, no matter their age, to be included in their number request for dining reservations.
Theresa, between now and up to 24-hours prior to your reservation at
Be Our Guest, 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. Guest can, also, call (407) WDW-DINE and speak to a Cast Member or use the Chat With Us feature through your My Disney Experience mobile app. Your party will clearly need larger and I can't guarantee they will be able to accommodate you at your current reservation time. You may need to adjust your time request and possibly the day if that is an option. Stay vigilant and keep checking, reservation availability changes daily and with a little bit of Faith, Trust and Pixie Dust and hopefully before the final petal on the rose drops, 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.
