Hi Sophie! Thanks so much for your question. You made an excellent decision to start planning ahead because reservations for Character Dining are known to go fast.
One of my family's favorite Character Dining experiences for breakfast is
The Crystal Palace. It's an all-you-care-to-enjoy meal with so many delicious options to choose from. My favorites are the Mickey waffles, puffed french toast, and the potato casserole.They even have an area for made-to-order omelets. Just talking about all of this delicious food has my tummy all rumbly.
Winnie The Pooh and all of your Hundred-Acre Wood pals will come around individually to visit during your breakfast. On our last vacation, we had so much fun with Tigger. When he came around to our table he lifted up my son and bounced around in circles with him. It's what Tiggers do best, after all!
Also, early reservations make for great photo opportunities. If you make a reservation before park opening, you can snap some coveted pictures of an almost empty Magic Kingdom.
When looking at dining options I always visit www.disneyfoodblog.com. They have great reviews and if you are a visual person like I am, you will appreciate that they include lots of pictures. They have a couple of reviews on the breakfast at The Crystal Palace, so if you want to look into it further, I suggest going there.
Feel free to stop by with any other questions and have a magical vacation at Walt Disney World!
