Hi Crystal,
Welcome to the Disney Parks Moms Panel! I can imagine the excitement in your household as you plan a visit to the Walt Disney World Resort!
Since special offers can vary, there is really no guaranteed best time to book. I start checking prices one year in advance and book our vacations at least nine months in advance. If a special offer comes out after you book, you can always call to ask if the offer can be applied to your reservation - it depends on availability.
Unfortunately, the printed customized maps are no longer mailed. To locate the printable map for Magic Kingdom, click on the
Magic Kingdom webpage. Currently, Cinderella Castle is at the top of the page. Underneath are small blue letters that say "Magic Kingdom Guide Map." The links to each park can be accessed on the Walt Disney World website under "Parks and Tickets." I will link the park maps for you here, but wanted you to know how to get to them in the future. You can also use the mobile app to get directions in the parks!
Magic, memories and Minnie Mouse hugs,
Donyell
