Hey there Amalia! Welcome to planDisney. I'm sorry to hear that you've had something come up that has an impact on your upcoming plans. We know that can be frustrating, but thankfully rebooking is easy!
You are correct that late June availability is currently unavailable on the calendar to book. This is because Disneyland Resort tickets are available 120 days out. You can go in and cancel your current reservations now and then wait for your new date to become available to rebook.
To cancel your current reservations, log in to your
Disneyland account. Hover over My Disneyland on the menu bar and click "Ticket & Reservation Details". From there you would select"View My Park Reservations" on the page and it will take you to a new page showing all the current reservations you have on that account. There you can cancel your reservation and a confirmation will be sent to you.
We know having to reschedule is never ideal, but the great thing is that there is always something exciting going on at Disneyland Resort whenever you choose to go. I recommend stopping by the
Disney Parks Blog before your new scheduled visit to see what up-and-coming things could be going on during your stay.
Thanks so much for stopping by planDisney, Amalia. I hope we see ya real soon!
Carrie
