Hello Brittney!
There are so many amazing options available for resorts at Walt Disney World. My favorite moderately priced resort in the Magic Kingdom Park area is
The Cabins at Disney's Fort Wilderness Resort. The cabins offer families plenty of space to spread out with a separate bedroom, large bathroom, fully-stocked kitchen, and living room area (complete with a Murphy bed). The cabins even have private, outdoor decks with grills. You can save a bit of money by having meals in your room, and Disney will do the dishes for you while you're out having a magical time with your family. We love to have breakfast at the cabin. We're fueled up and ready to start our day, and the savings add up.
The resort offers loads of activities and amenities, but my favorite part is the tranquil, quiet surroundings. When you're at Fort Wilderness, you feel like you're miles away from the hustle and bustle of the Theme Parks, but you're really just a quick boat ride from the gates of Magic Kingdom Park. It's such a fantastic place to stay.
I hope this helps, Brittney. Please come back and see us again real soon.
Pixie Dust,
Ashley
