Hi again Sherri,
I always start to get a little excited once I can make my Advanced Dining Reservations!
No penalty will be imposed for not turning up to an advanced dining reservation unless it has been guaranteed with a credit card ahead of time. It is however always courteous to cancel your reservation ahead of time if you are able to do so as that way another guest who has been unable to get a reservation will be able to enjoy the meal at the restaurant in question.
Whenever I am asked about restaurant reservations for picky eaters, I always suggest places where buffet service is offered as there will be a vast choice of food available with something for everyone.
If your daughter still enjoys character meals then I would suggest either Chef Mickey's or Donald's Safari Breakfast.
For something a bit different, you could try
Trails End at Disney's Fort Wilderness Resort & Campground or
Biergarten in the Germany Pavilion at Epcot
I hope that this has given you some ideas and wish you a magical trip!
