Hi Hannah,
Cinderellas Royal Table is one of my favourite restaurants at Walt Disney World - there is something simply enchanting about dining inside Cinderella Castle.
You can absolutely make advance dining reservations for Cinderellas Royal Table at 180+10 days if you are staying at a Disney Resort hotel. I have done this many times in the past without any problem.
In order to ensure that you get a reservation at this extremely popular restaurant, I would strongly recommend that you are logged in to the Walt Disney World website and on the "
Make A Reservation" page at exactly 6am EST (which is 11am for those of us here in the UK)
If you make your reservation online, you will get an hours head start on those guests who will be calling to make their advance dining reservations when lines open at 7am EST (12 noon UK time)
Good luck and if you have any other questions, please do not hesitate to contact the Moms Panel again.
Wishing you a magical trip!
