Make sure you keep your wallet in your front pocket instead of the back pocket. When you get off a ride make sure you don't leave any belongings behind. Don't kick your feet out when on a floor less coaster because someone else can kick your legs and hurt you.
Disneyland itself is relatively safe compared to the commute to get to the park. Do NOT walk to the park even if it's walking distance. Hire a shuttle or Taxi.
