Hi there, Fairy Grandmother Julie!
What a magical time you are planning for your grandchildren.
Julie, I am happy to tell you that you are able to purchase
Florida resident discounted tickets for your grandchildren as long as they are minors.
Any adults must
provide proof of residency to activate their Florida resident tickets, so while you can purchase tickets for your minor grandchildren, older grandchildren, as well as your children, will need to purchase standard tickets. Speaking of providing proof of Florida residency for tickets, you must also be present with your valid Florida ID or other identification to activate their tickets for them on the first day that they are used.
Julie,
Disney Park Pass system reservations are required for theme park entry. Since reservations are limited, I would suggest that you purchase your tickets and make your reservations as soon as possible.
I hope that this answered your question, Julie. Please come back here if we can help answer any other questions to make your trip practically perfect in every way.
Sarah B.
