Hi Emily,
Thank you so much for visiting the Disney Parks Moms Panel with your question.
I agree with you, having an extra bathroom in a one-bedroom villa is really helpful, especially when you have five guests in that villa! You are correct, this configuration is available at
Disney's Animal Kingdom Villas - Kidani Village. Another resort where you can find a one-bedroom villa that sleeps five guests and includes a second bathroom is
Bay Lake Tower at Disney's Contemporary Resort. I have stayed in a one-bedroom villa at both of these resorts, and I find that they are spacious and comfortable. Either way, I think you will be quite happy with your resort choice!
If you find that you enjoy these larger accommodations, you might want to consider
Disney Vacation Club membership. Disney Vacation Club is Disney's vacation ownership program, and many of the accommodations are larger and include multiple bedrooms and bathrooms.
I hope that this information is helpful for you, Emily. Have a wonderful time planning your magical vacation, and please do let us know if you have any further questions.
