Hi Alicia,
Breakfast at Chef Mickey's is a lot of fun! It is a great way to meet Mickey Mouse and his friends.
You can absolutely eat at
Chef Mickey's without Disney theme park tickets. Chef Mickey's is located inside of Disney's Contemporary Resort, which is a resort hotel and therefore not inside of a theme park. All guests, no matter where they are staying, are welcome to enjoy any restaurant at a Walt Disney World Resort hotel without Disney theme park tickets.
Since Chef Mickey's is a popular dining location, I suggest that you make your reservations as soon as you can. You can make your dining reservation 180 days before you dine. You can do this online at the
Disney Dining website, or you can call 407-WDW-DINE (407-939-3463).
I hope that this information is helpful for you, Alicia. Have a great time planning your vacation, and please do not hesitate to ask if you have any further questions!
