Hello Iris!
Thanks for visiting us here at the DIsney Parks Moms Panel! We are always eager to help Guests plan exciting trips to the
Walt Disney World Resort. Feel free to come on back with any additional planning questions.
With regard to a seating time for
Cinderella's Royal Table, I would recommend the 7pm reservation if you are interested in prime viewing for Wishes! Nighttime Spectacular. Either time should be great, however. You should be able to get a nice view from inside Cinderella Castle, but you will not get the complete vantage point from which you can appreciate every aspect of the "show." Although it can get quite crowded, to get the optimal view, I like to stand near the Castle "hub", or near the end of Main Street, U.S.A.
There you have it! I hope this helps.
I wish you a truly magical vacation, Iris!
