Hiya Pal!
Thanks for bringing your question to the Disney Parks Moms Panel. While there isn't a direct option between these two locations I do have a couple options that I think will help you out!
If you want to strictly rely on Disney Transportation your best bet is to take a bus from
Disney's Coronado Springs Resort to
Disney's Animal Kingdom. From here you'll get off that bus and transfer to a bus that can take you to
Disney's Animal Kingdom Lodge. You can also go to Epcot or Disney's Hollywood Studios and make the same transfer, but you'll find that getting there via Disney's Animal Kingdom will prevent you from going out of your way.
Another option is to take a ride sharing service, like Uber or Lyft. Based on my experience this will be a relatively inexpensive trip and you'll save time doing so. Depending on when you visit you may also want to check to see if the
Minnie Van Service is available from Disney's Coronado Springs Resort. At this time it is not, but they are constantly adding new locations so you can double check with the Cast Members at the Conceirge to see if its an option.
Please let us know if you have any other questions before your upcoming visit to Walt Disney World Resort!
