Hello Betty,
Welcome to the Disney Parks Moms Panel and thank you for bringing us your question. It's so fun to talk to a fellow Disneyland planner like myself!
Unfortunately, the Disneyland Resort does not mail out the actual park maps and there isn't a function on the Disneyland Resort website to print the Disneyland Park or the Disney California Adventure Park maps. I'm at a loss really at how to direct you on how to get some, unless you have a local friend that can mail you four park map sets for your "survival kits."
I suggest putting a cute card in all the kits that suggests them to study both park maps online until their magical vacation arrives. They can
select Attractions by Thrill Level, Interests, Age Interest, Height, and Accessibility & Advisories. Then when they arrive at The Happiest Place on Earth, they will feel like they have stepped into their second home. Upon entering the turnstiles, Cast Members can give each of the family members their very own Disneyland Resort park map as well.
I hope this helps and that you have a pixie dusted visit. If you have any more questions, please visit me here at the Disney Parks Moms Panel and let me know how I can help you plan your magical vacation.
Wishing you magic, Betty!
