Hi Jennifer!
I bet your children are so excited about their first visit to Walt Disney World Resort. How exciting for them!
It sounds like you've got a great plan for your first day. When you are ready to leave Magic Kingdom park to head over to
Disney's Wilderness Lodge for dinner at
Whispering Canyon Café, you can take the water taxi that departs just outside of the entrance to Magic Kingdom. It's a short boat ride to Wilderness Lodge and the children will probably enjoy it. When you're finished with dinner and are ready to return to your resort, you can either go back to Magic Kingdom to get on the bus to
Disney's Coronado Springs Resort or take a taxi. The attendants at the entrance of Wilderness Lodge will be happy to assist you in getting a taxi that will accommodate your whole family. After a long day with three children, this may be the easiest and quickest way back, but you can definitely wait to see how everyone is holding up after dinner.
I really hope your family has an amazing first trip to Walt Disney World Resort. Be sure and get "1st Visit" buttons when you check-in so everyone will know you are celebrating! If you have any other questions, don't hesitate to let us know.
Have a magical day!
