Hi, Ashley!
Welcome to the Disney Parks Moms Panel, and thanks for your great question. I’m glad to hear you’re planning to dine at ‘Ohana and Chef Mickey’s this winter.
Yes, here should be complimentary bus transportation available to you on the mornings of your meals. On the day before your first breakfast, ask a Cast Member at your resort's Guest Services desk where and when you can board the "breakfast bus” to take you to your early reservation. If Magic Kingdom Park is scheduled to open at 8:00 a.m., you can also board the earliest regular bus at or just before 7:00 a.m. Then you can take the monorail to Disney's Contemporary Resort for Chef Mickey’s and Disney’s Polynesian Resort for ‘Ohana.
If you happen to miss your bus to Magic Kingdom Park or want a quicker, more direct mode of transportation, you can also take a taxi from your resort straight to Disney’s Contemporary Resort.
I hope this helps, Ashley, and that you have a perfectly pixie-dusted visit to the Walt Disney World Resort!
Wishing you magic,
Courtney
