Welcome to planDisney Rolando!
I totally understand that plans and schedules change, and the good news is that there usually is a good amount of time before
standard Disneyland theme park tickets expire. I would reference your confirmation email from when you purchased your theme park tickets, there should be an expiration date listed. I recently purchased a Multi-Day theme park ticket, and there is a separate paragraph for my "Multi-Day Ticket Expiration" that clearly states the expiration date, and any terms and conditions.
You will want to ensure that you make your theme park reservations for your new trip dates as soon as you can, and the
theme park reservation availability calendar will be a great resource for you. If you are having trouble locating your ticket expiration date, you also can reach out to a helpful Cast Member on the
Ticket Services line.
I also highly recommend exploring the
Disney Parks Blog prior to your next Disneyland Resort or any Disney Destination visit! It always gets me even more excited for my trip when I can read up on the special events or food items I'll get to experience during my vacation.
I hope this information is helpful for you, Rolando! Don't hesitate to
come back to planDisney if we can help with any other questions throughout the year.
Have a magical day!
Melissa
