Hi there, Valerie!
Welcome to planDisney and thank you for coming to us with your question! I must admit that I'm a little envious of other Southern California residents who are able to visit the Parks much more easily than I. And the Special Southern California Resident Ticket Deal is a fantastic offer! You get a 3-day, 1-park per day ticket that can be used on non-consecutive weekdays through May 25, 2023.
In response to your question, you may indeed switch your park reservations at any time and it is very simple to do so. First, I would recommend checking the availability calendar to make sure that the dates you desire are free. In order to cancel and re-schedule your reservations, follow these steps:
- After logging in to your Disneyland account, navigate to the Tickets and Reservations page. Select "Make Park Reservations."
- On the next page, select the date that you would like to cancel and click on "Cancel Reservation." Confirm this choice on the next page. You will need to repeat this step for each day that you would like to cancel.
- Back at the Tickets ands Reservations page, click "Make Park Reservations" again and then proceed to select the date and Theme Park that you would like.
And that's all there is to it! I certainly hope that you are able to reserve the days that you want. At the time of this writing, the calendar appears fairly open. For your visit on March 17, be sure to catch Wondrous Journeys, the new nighttime spectacular at Disneyland Park. According to the Entertainment Schedule, fireworks will be part of the show, weather permitting. In addition, the Food & Wine Festival will be running at Disney California Adventure from March 3 to April 25. The Foodie Guide was just released and there are so many yummy dishes on it, especially that Pineapple-coconut Churro. It's like they put all my favorite things together into one dessert!
I hope you found this information helpful, Valerie, and that you are able to change your reservations without issue. Please feel free to visit us again here at planDisney if you have any more questions!
Have a Magical Day!
