Hi James,
My little princess loves the Character Dining at
Hollywood & Vine in Disney's Hollywood Studios. You can't beat an experience where you hug Doc McStuffins, Sofia the First, and indulge in copious amounts chicken nuggets and chocolate from the chocolate fountain. It's a preschooler's dream!
While Hollywood & Vine does offer Character appearances and entertainment, the Disney Characters are only available for breakfast and lunch. You didn't specify the time of your Advanced Dining Reservation, but if you made one for either of those meals, you are good to go.
I hope this answers your question, James. If you have any other questions while planning your magical vacation, please feel free to ask us at any time. We're always here to help.
Have a fantastical Disney day!
