Hello Samantha and thanks for bringing such a great question to the Disney Parks Moms Panel.
I have to say that it's always an added pleasure for me to assist a fellow Guest from the United Kingdom with their jolly holiday plans to visit Walt Disney World Resort.
September and
Autumn at Walt Disney World Resort is such a great time to visit and although you haven't mentioned which Disney Resort you'll be calling home, I've made a guess that you'll be staying
in the islands at the beautiful
Disney's Caribbean Beach Resort. I guessed this Resort as due to the scheduled refurbishments at Disney's Caribbean Beach Resort I understand that some Guests have been offered
Disney Gift Cards which I think is the
$75 you're referring to.
On your behalf I just spoke with a Cast Member in
Disney Resort hotel Reservations by dialling the free-phone number contained within this
Walt Disney World Resort Phone Directory who confirmed the Disney Gift Cards will be provided to the Guests
in full to cover the length of stay upon Resort check-in.
I hope I've answered your question correctly! If not please don't hesitate to return to me so that I may assist you better with your upcoming September holiday to
Walt Disney World Resort.
Have a great Disney day.
~ Jane
