Hi Jeremy,
Thank you so much for visiting the Disney Parks Moms Panel with your planning questions. I am glad that you are considering how to get around on your Walt Disney World vacation before you arrive. Planning ahead will make the days go more smoothly when you are on vacation!
To get from
Disney Springs to
Magic Kingdom, I suggest that you take a bus from Disney Springs to Disney's Contemporary Resort. I would leave about 45 minutes for this journey, which would include a possible short wait time for a bus at Disney Springs. Then, from Disney's Contemporary Resort, it is about a 10-minute walk to Magic Kingdom. You could also choose to take the monorail or a boat for this leg of the trip, but I think that walking is likely the quickest way for this to happen.
There is
bus service from theme parks to Disney Springs after 4:00 p.m. if you need to head back to Disney Springs. Of course, from Magic Kingdom you could also take Disney transportation directly back to a Walt Disney World resort hotel.
I hope that these thoughts are helpful for you, Jeremy. Have a wonderful time planning your magical vacation, and please do let us know if you have any further questions.
