Hi there, Sucheera. Thanks for stopping by planDisney with your question. I'm glad you're here!
I'm glad you are planning ahead for the best day possible at the Happiest Place on Earth. The Disneyland Mobile App has a convenient way to check for rides with drops that you may wish to avoid. From the Disneyland app home screen, select the pin drop icon, which is second from the left at the bottom of the screen. This will open the Disneyland Resort map. At the top, make sure "Attractions" is selected, and then click the three-line slide bar to open the filters. This opens up the filters that allow you to select rides to your liking. You can select rides with big drops, small drops, thrill rides, spinning rides, and more to see which you might like to ride... or not! There is also a ride search function on the Disneyland website!
In my experience, here are rides with drops or with heights that you may wish to avoid:
Disneyland Park
California Adventure Park
You are welcome to read short blurbs about each of these rides on the Disneyland website. I think it would be a great way to set expectations about which rides might be the best for your visit.
Sucheera, the lists above may seem long, but I assure you, there is still so much magic to have at the Disneyland Resort. Be sure to check out the live entertainment on Main Street and Buena Vista Street, or enjoy one of the shows or the Animation Building in Hollywood Land. My family also loves Animation Academy and Storytelling at Royal Theatre. You can check showtimes and character meet and greet times in the Disneyland App!
Thanks again for stopping by, Sucheera. Please let me know if you have any other questions or need more suggestions for your magical day. I would love to help!
See ya real soon,
Melissa
