Greetings Jessica!
Thanks for submitting your question to the Disney Parks Moms Panel!
Magic Morning at Disneyland Park is a perfect time to enjoy the Happiest Place on Earth without the large crowds!
It's my favorite time to take photos of the kids in front of the iconic Sleeping Beauty Castle ride as many of the more popular attractions before the lines get long!
Here's what you need to know in regards to your theme park tickets.
The Magic Morning feature is offered to guests who purchase a 3+ day tickets.
If you paid extra to add the Park Hopper option to your tickets, then you're free to visit both Parks on the same day without a problem.
However, if you do not have the Park Hopper option, then you wouldn't be able to visit
Disney California Adventure after activating your ticket at Disneyland during Magic Morning hour.
I hope this helps.
Wishing you a Magical time and lots of ChEARful experiences!
