Greetings, Monserrat. Welcome to planDisney! I'm sorry to hear that there is rain in the forecast on the day of your visit. I am happy to help walk you through modifying your reservation!
If you have a
single or multi-day theme park ticket, you will want to log into your MyDisney account on the
Disneyland Resort website. Click the "My Disneyland" tab at the top right of the page and select "Theme Park Reservations" in the menu. Then, select the "Make or Modify Park Reservations" button and you'll see an "Upcoming Theme Park Reservations" section. From here, you'll want to go to your reservation on the 5th and click "Modify Reservation" to change your theme park for the day. Please be aware that the theme park reservation calendar is constantly changing, and you will want to book soon to ensure your new date is available.
Monserrat, I know rain can be less than ideal but I want to let you in on a little secret: I actually love rainy days at Disneyland! Ride wait times are shorter and there are lighter crowds. I love ducking into the Main Street Cinema in
Disneyland Park and the Animation Building in
Disney California Adventure Park to beat the rain (and the heat on some days). There is still so much to experience! Even if you aren't able to modify your reservation date, I think you could have a swell time.
I hope this helps you modify your reservation. Please come back and
visit me again sometime!
See ya real soon,
Melissa
