Hi Jennifer,
Yes, indeed, The Mara at the Animal Kingdom Lodge's Jambo House
does serve breakfast. Breakfast is also available at
Boma at Jambo House.
Animal Kingdom Lodge's Kidani Village, however, does
not have a place that serves breakfast. You can order breakfast from in-room dining, though. You can also purchase pre-packaged food items (like cereal and toaster pastries) and beverages at Johari Treasures.
When we stayed at Kidani Village, we just walked over to The Mara to eat; you can also catch a bus to Jambo House from Kidani Village if you'd prefer to not walk.
Thank you for visiting the 2012 Walt Disney World Moms Panel; please let us know if we can help again.
