Hi, Laura!
Your darling princess will not need to show any proof of age when entering either theme park at the Disneyland Resort. Since she is not yet 3 years old, she will not need a
theme park ticket. Hooray for being 2 years old!
There is a lot of walking at
Disneyland Park and
Disney California Adventure Park. You may want to bring a stroller from home, or
strollers are available for rent outside the main gates of Disneyland Park. Once in the park, you will find many stroller parking areas to park your buggy when enjoying a meal or going on an attraction. When your stroller is unattended, please take all valuables with you.
Kids get tired and need a break (and the parents do, too!) so feel free to take a mid-day break back at your resort for a nap or a splash at the pool. When you return later in the day, show your park ticket to be re-admitted. If you plan to switch parks mid-day, make sure you add on the Park Hopper option when purchasing your tickets.
Wishing you and your family a magical visit to the Happiest Place on Earth!
Cathy
