Hi Lara!
Welcome to the Disney Parks Moms Panel. I can't wait for you to visit the Happiest Place on Earth this summer. You picked such an exciting time to visit the Disneyland Resort, because the brand new
Pixar Pier in Disney California Adventure Park will have just opened a few days prior. This exciting area features dining and attractions featuring everyone's favorite Pixar Characters and films.
You can confirm the park hours, entertainment times, and attraction refurbishments on your days of travel by visiting the
Daily Events Schedule online. For June 27, 2018 I am seeing that Disneyland Park is open from 8:00 AM to 12:00 AM midnight and Disney California Adventure Park is open from 8:00 AM to 10:00 PM. If you are staying at a
Disneyland Resort Hotel, you have access to an Extra Magic Hour that morning from 7:00 AM to 8:00 AM at Disney California Adventure Park.
When you
purchase park tickets online, you can select the number of days you will be visiting the parks as well as if you'd like to only visit one park per day or have the option to hop between parks each day. Since it sounds like you are visiting one day and would like to experience the magic of both parks, I would definitely suggest you purchase a Park Hopper ticket. You can easily hop from park to park all day since they are only footsteps apart.
I hope this helps, and please feel free to return if you have any other questions!
