Hi there, Bonnie! Thanks for stopping by the Disney Parks Moms Panel with your question!
You'll be glad to know that the Disneyland Resort is incredibly accommodating to nursing mothers. The private nursing areas in the
Baby Care Centers do indeed have outlets to plug in your pump. If you will be bringing your little one along, you can also use the Baby Care Centers to change diapers, rock your baby to sleep, or to just take a short break. They also sell over-the-counter medications and baby essentials should you need anything. Additionally, there are sinks and microwaves in the centers if you use those microwavable sanitizing bags to clean your pump parts in between sessions.
I suggest
renting a locker to store your pump and a cooler for your expressed milk. There are lockers not too far away from the Baby Care Center inside Disneyland Park, or you can rent a locker in the area right outside Disneyland Park if you will be park hopping.
I hope this helps! Have a magnificent time at the Happiest Place on Earth!
