Greetings Talia, I'd like to wish you a Royal welcome to planDisney!
Take it from a Prince, there's really something extra-special about being able to have breakfast in a castle, and successfully snagging a spot at
Cinderella's Royal Table is a wonderful way to start off any Disney day! Looking at the
Park Hours for the date that you've indicated, this means that you could be among some of the first folks entering
Magic Kingdom Park in the morning and even catch a glimpse of
Let The Magic Begin as Character friends welcome everyone in front of Cinderella Castle.
When it comes to where you'll be dining at Cinderella's Royal Table, specific seating requests may not necessarily be accommodated nor guaranteed; however as an earlier seating you could have luck asking the Cast Members and letting them know as you check in that you'd like adjacent tables. (Be prepared in the event that they say that they're unable to do so depending on availability or management policies on the day of your visit, but I always find that kindness and flexibility can go a long way when it comes to them trying their best to make it happen for your group.) On my previous visit I spotted some great bench seating options especially along the walls that may be easier for your entire party to be able to sit close to each other, and it certainly never hurts to ask and also recognize any Cast Member who goes above and beyond to make a little magic for all of you! Just make sure that you have the names of the Primary Guest for each reservation as you check in together, to make it easier for them to look up.
As an added Princely Tip, I recommend having a bag handy for any royal trinkets that you may pick up by the time you're ready to depart from your meal just in case you want to keep special things like magic wishing wands or swords safe as you
head onto any thrill rides after breakfast! Hope this helps, Talia and that your entire party can enjoy a most magical meal together at the start of your morning at the Most Magical Place on Earth.
Say hello to my Princess pals for me!
Prince
