Hello Samantha! How exciting that you have a trip to the Disneyland Resort coming up!
I'm not sure exactly which month your trip is planned for, but if you have a
theme park ticket and
theme park reservation for March 18 for example, then your ticket will allow you admission the morning of March 18. Most likely the parks close at midnight or even earlier, so you would not be allowed entrance into the parks at midnight on March 17 since they would be closed for the evening. You can check the
hours & events calendar leading up to your trip to see the exact hours for both
Disneyland Park and
Disney California Adventure Park.
There are so many exciting events taking place throughout the entire Disneyland Resort this year! I am most excited about the return of the
Disney California Adventure Food & Wine Festival, as well as Pixar Fest. If you love to try all kinds of food and beverages, I highly recommend visiting Disney California Adventure Park during the festival if that coincides with your trip dates. There are so many tasty things to sample, some of my favorites include the Grilled Top Sirloin at the Garlic Kissed booth, and the Blueberry Pancake Cold Brew at the Golden Dreams booth.
Pixar Fest will be taking place throughout the entire resort, and I can't wait to catch the new "Better Together: A Pixar Pals Celebration!" daytime parade at Disney California Adventure Park. It truly will be a wonderful celebration of friendship and beyond!
I hope this information helps answer your question, Samantha!

Have a magical day,
