Hey there, Jacqueline!
Welcome to the Disney Parks Moms Panel, and thanks for your question. I cannot wait for your trip to the Happiest Place on Earth!
My son is a HUGE fan of PJ Masks on Disney Junior! Last year he even dressed up as Catboy for Halloween. While we wish there was some more representation of this show and these Characters in the parks, I haven't seen any PJ Masks merchandise at the Disneyland Resort. Your best bet would be to check your local Target, Walmart , or Old Navy stores as these have been locations where I have found PJ Masks toys and clothing for my son in the past.
If you have children that are fans of Disney Junior programming, you won't want to miss the
Disney Junior Dance Party! in Disney California Adventure Park. This show is a great opportunity to let your little ones release some energy to fun music while giving parents a much-needed chance to rest their feet. Nearby you can usually meet some Disney Junior Characters throughout the day, so you'll definitely want to check the
Disneyland app each morning for a list of Character appearances.
I hope this helps, and please return if you have any other questions. Have a Fantasmic day!
