Howdy Olivia! Thanks so much for your question!!
You are going to love the
Treehouse Villas!! I'm so excited for you!!
I was told by a Cast Member that it takes 10 minutes to get to Magic Kingdom if you are in your own personal vehicle and 15 minutes if you are using the Disney Buses.
However, if you are trying to make it to a dining reservation or other specific event, I would plan on an hour (at minimum) from the time you leave your villa just to ensure you have enough time to get to the Magic Kingdom.
The Treehouse Villas are amazing! You are surrounded by a lush forest in your own vacation hideaway. With the seclusion, comes a bit of distance to and from the rest of the resort. If you will be using Disney Transportation to get to Magic Kingdom (or other Walt Disney World Resort locations), you will either walk, boat or take an internal shuttle to Disney's Saratoga Springs Resort and Spa. From there, you will be able to catch a bus to the theme park.
Thanks again for your question and please let me know if you need any further information.
Have a magical day!
