Hi, Tereza! Welcome to planDisney and thank you so much for sending this question to us. I'll be happy to help you get some answers as you continue planning your visit to Disneyland Resort.
Tereza, it should be no problem to
modify the park reservation for your new visit date, so long as there are park reservations available. You can check this on the
Park Reservation Availability Calendar before you make any changes if you like. Now, Tereza, if you have a multi-day ticket to visit the theme parks, you can simply log in to your MyDisney Account and select the "modify reservation" button in the "
My Plans" section. You'll want to do this for each Guest in your travel party. If you happen to have a dated,
1-Day ticket then you will want to ensure that your new visit date falls within the same ticket tier or a lower one, otherwise, you will need to pay to upgrade the ticket. However, I have some good news because I checked to see that July 15 and July 16 both correspond to Tier 4 at this time, which means that you should be able to seamlessly modify your park reservation for your new date without any upgrade.
I hope this is helpful guidance, Tereza. If you'd like to speak to a Cast Member by phone about these modifications or anything else about your park reservations, please feel welcome to call the
Tickets line. If we can assist with anything else, here at
planDisney, please don't hesitate to come back and share another question with us!
Wishing you Wondrous Journeys,
