Hello there, Clarissa! Thanks so much for stopping by planDisney with your question. Welcome!
The weather sure has been making a lot of plans more complicated lately, hasn't it? I'm sorry to hear the forecast is showing some less-than-favorable weather for your upcoming visit. That's the great thing about
theme park ticket reservations, they can indeed be canceled and rebooked if plans need to change. However, I just took a peek at the
Theme Park Reservation Availability Calendar and at the time of writing this, it looks like all reservations are booked for March 30, 2023. Now, the calendar is fluid and that means it's totally possible that Guests could cancel reservations and they could open up for reserving. I recommend watching both the calendar and the weather forecast closely. The forecast changes so quickly here!
In order to change your reservation, you would need to cancel your current one first. You can do that in the
Disneyland app by tapping on the bottom right-hand corner where the three horizontal lines are. Then tap "Future Plans" and tap on the reservations. This will take you to a page where you have the option to cancel. As I said before, currently there are no reservations for the date you were looking at so be sure you have checked the calendar and see there are reservations for both the date and park you are wanting to visit before you cancel.
Clarissa, I hope reservations open up and you can change plans. However, I think a rainy day at Disneyland is better than a day not at Disneyland and there is plenty of magic to enjoy on a rainy day in the parks. The last few visits I've had were rainy days. Just bring a poncho and make the most of it!
