Hi Rhonda,
Thank you so much for visiting the Disney Parks Moms Panel with your question! You have chosen two unique resorts for your vacation. My family and I stayed at a Treehouse Villa at
Disney's Saratoga Springs Resort & Spa last year, and it was really fun to have our own haven tucked away in a serene and wooded environment. Whether you are staying at
Disney's Animal Kingdom Villas - Jambo House or
Disney's Animal Kingdom Villas - Kidani Village, these resorts feature rich and beautiful decor and the ability to see exotic animals outside of nearly every window!
Your refillable resort mugs should be good for the length of your stay at Walt Disney World. Even if you change resorts during the stay, as long as you are still at a Walt Disney World resort, your refillable mug should still be good. There is great information about the refillable mugs at the unofficial site disneyfoodblog.com. If you visit that site and search for "refillable mugs," you will find this information.
I hope that these thoughts are helpful for you, Rhonda. Have a great time planning your magical vacation, and please do let us know if you have any further questions.
