Hello, Marlyn!
Welcome to planDisney, and thanks for sharing your question with us!
The Disneyland Resort is excellent in December, and I hope you can enjoy its holiday atmosphere as soon as possible. Remember to
explore the Disney Festival of Holidays at Disney California Adventure Park, the unique entertainment, and the attraction overlays. They're genuinely unforgettable!
I truly hope you can enjoy the holiday vibes at the Disneyland Resort, Marlyn, but don't worry if you have to change your dates.
Current ticket rules state that 1-day tickets are valid for dates in the same or lower tier. So if you change the dates on your reservation, remember to check your ticket's expiration date and if it's valid for your alternative travel dates. On the other hand, multi-day tickets must be used within 13 days after first use or by the stated expiration date, whichever occurs first.
You can also apply the amount paid for any wholly unused, expired ticket (except for special event tickets) toward a new ticket at the current price if the new ticket price is equal to or greater than the amount paid for the original ticket.
I will be crossing my fingers for a sunny December so you can have a blast at the
Disneyland Resort, Marlyn!
May the magic be with you,
Julie
