Guest Services
You'll find California Adventure Guest Services just to the left of the main entrance. No matter what you need, this is the place to go. They can cash a check, supply an audiotape tour or Braille guidebook, lend you an Assistive Listening Device or closed captioning activator, answer your questions, or wish you a happy birthday. They'll try to help, no matter what you need.
The Lost and Found department is located outside the California Adventure entrance, to the left behind the wall. The Baby Care Center and First Aid Station are in Golden State, near the Mission Tortilla Factory. To get there from the entrance, follow the walkway that goes to the right of Sunshine Plaza past “a bug's land.”
Disney security is highly trained in dealing with lost child situations. If a child (under age ten) in your party gets lost, seek help from Disney security or report the missing child to any Disneyland Cast Member and follow their instructions. The missing kid is likely to end up at Guest Services. Guests over ten years old can leave a written message at Guest Services near the entrance.
