Hi Kim, welcome to planDisney!
I truly hope you're able to make your flight! I'll do my best to send over all the Disney Magic I can! But back to your question,
multi-day tickets purchased this year must be used within 13 days of first use or by January 12, 2024, whichever occurs first. So in your situation, even if you miss the first day of your
theme park reservation, you can absolutely still attend the remaining two days you have reserved. You can then book a new reservation to use your final third day of your ticket. However, the third day must be within 13 days of first use.
And I highly recommend monitoring the
Theme Park Reservation Availability Calendar for availability if you need to find a reservation for your final third day. Also, even if reservations are fully booked for the days you are interested in, keep checking the calendar as reservation availability is fluid and constantly changing.
And lastly, have you heard about all the amazing experiences that have returned to the
Disneyland Resort? The traditional character meet and greets have returned, which means Mickey and all his Pals are ready to give out the best hugs and sign your autograph books! And many of the fantastic nighttime experiences are back as well!
The Main Street Electrical Parade,
Disneyland Forever fireworks,
World of Color, and my personal favorite,
Fantasmic! have all returned! Hopefully, this gives you something exciting to look forward to!
See ya real soon!
