Greetings Lisa!
A trip to the Happiest Place on Earth at the end of June with your parents who haven't visited the
Disneyland Resort in several decades sounds Magical!
Generally, the parade and show schedules are released 60 days in advance.
For
dining reservations, guests can usually book their favorite restaurant up to 60 days in advance.
Since you're planning your trip to the Disneyland Resort at the end of June, I'd wait a few days or so and check back on the Disneyland.com website to see if the parade schedule has been listed.
Keep in mind the
Disney California Adventure Park features a sensational nighttime spectacular, World of Color!
Currently, there are some fabulous dinner and dessert
package offerings that come with preferred viewing vouchers for World of Color. You should consider one of these packages for an unforgettable dining and viewing experience.
I hope I've answered your question.
Thanks for visiting the Disney Parks Moms Panel!
A Very Merry Unbirthday to you!
