Hi Becky,
What a wonderful aunt you are taking your niece and nephew for their first trip to the Walt Disney World Resort. You will have such fun being able to experience the magic with them. The maps were a very popular addition to planning your vacation, but unfortunately, they have been discontinued.
If you'd like everyone to get in on the planning of your vacation,
My Disney Experience either online or via the free phone app, may be just what you are looking for. You are able to view maps of all the Theme Parks and resort areas, restaurants, attractions and more. I don't know how old your niece and nephew are, but if they are like most kids, they are very tech savvy and may enjoy using this app.
Thanks for visiting the Moms Panel and hope to see ya real soon!
Leanne T
