Hello Beatriz and welcome to the Disney Parks Moms Panel.
Oh boy! I'm super excited to know you're planning on spending an extra magical Christmas Eve at the
California Grill, it's sure to be totally tinseltastic in every way!
I absolutely love dining in the
top of the world ambiance of the California Grill and for me the observation deck truly is one of the best vantage points to view Happily Ever After from.
I believe that approximately an 7-8pm Advanced Dining Reservation time would suit perfectly and don't forget that it is Christmas Eve after all and you'll need to be tucked up in bed and sound asleep before Santa can visit!
I'm happy to share that on your behalf I've taken a peek at the current
Park Hours & Calendars which are posted for Sunday 24th December 2017 and can see that at present
Happily Ever After is scheduled to begin at 9pm. However, I think it always good to remember that things are always subject to change at Walt Disney World Resort so please do check back closer to December to re-check the schedules for any updates.
Wishing you a very happy
Holidays at Walt Disney World Resort.
