Hi Kimberly! Just one month to go until your Walt Disney World vacation! How exciting for you and your family. Here is a link for the Walt Disney World calendar beginning
May 22 at Walt Disney World, where you can check each park's link and it will tell you where and when the characters will be meeting with guests. I hope you find this helpful in your planning.
Kimberly, if you haven't already done so, you'll want to download the free app for your smartphone; My Disney Experience. Not only can you link all of your reservations, you can check park maps, hours, attraction wait-times, character locations, and even make same day dining reservations, to name just a few of the features. It will be an invaluable tool for your vacation, and will make things so easy!
Thanks again for your question, and please let me know if I can assist you further. Have a magical day!
Kristen
