Hello Lena, and welcome to planDisney! How exciting that you'll be visiting the "Happiest Place on Earth" here soon!
If you were able to update your
theme park reservations to your new desired date, you should be all set, and you will not need a new barcode for your
theme park tickets. I would double check your
Disneyland app to ensure that your reservations are for the correct park and for the correct dates, and then you're ready to unlock the magic! If you'd like to check availability for either park or need to change your reservation date again, the
theme park reservation availability calendar will provide you with all of that information.
I hope you get to visit the recently reopened
Mickey's Toontown in
Disneyland Park during your visit! I cannot wait to explore
CenTOONial Park, get a chance to meet Pete and Clarabelle, and try some of the new food offerings at
Café Daisy. Everything I have seen so far just looks so colorful and playful for guests of all ages.
I hope this information was helpful for your upcoming trip Lena, I'm wishing you and your family the most magical trip!
Have a wonderful day!
Melissa
