Welcome to the Disney Parks Moms Panel, Veronica. Thanks for stopping by and I hope you're having a Tigger-ific week.
I'm glad to hear you'll be visiting the Disneyland Resort in less than a month. The minimum age for children to ride by themselves is 7 years of age. Otherwise, they will need to be accompanied by someone who is 14 years or older. In your case, the 10-year-old can go on rides alone but won't be able to take the 5 year-old without someone older than 14 years of age.
There are many
attractions without height requirements in Disneyland Park and Disney California Adventure Park that all of you can enjoy together. Some of my family's favorites that cater to Guests of all ages are: Peter Pan's Flight, Dumbo the Flying Elephant, Heimlich's Chew Chew Train, Flik's Flyers and Mickey's Fun Wheel.
I hope this information is helpful for you, Veronica. If you need further assistance or tips to plan an unforgettable trip to the Happiest Place on Earth, please swing by the Panel again.
Have an enchanted day,
Kiki
