Hi there, Carolina!
Welcome to the Disney Parks Moms Panel. I can't wait for you to visit the Happiest Place on Earth with your little one.
While unfortunately there is not a location to store a standard car seat at the Disneyland Resort, I do have a few suggestions for you. First, if your child is an infant, I recommend using a car seat caddy stroller base to use your infant car seat as a stroller in the parks. Up until my son was a year old we chose to travel in this way so we could conveniently have his car seat with us at all times. If your child is old enough to utilize a small travel-sized booster car seat, this may fit inside one of the
locker rentals located in the esplanade between the parks. As a Guest of a Disneyland Resort Hotel or Good Neighbor Hotel near the parks, you are always more than welcome to check your car seat at the hotel's bell desk even if you arrive before check-in. If none of these suggestions apply to you, you may want to actually consider renting a car for the day so you can bring your own car seat without the stress of worrying where you will store it. There are
two convenient parking areas located at the Disneyland Resort: Mickey & Friends Parking Structure and Toy Story Parking Area where you can park your rental car. Sometimes for us this is our favorite option as we also have more freedom with our own vehicle.
During your time at the parks, don't forget that there are convenient
Baby Care Centers located in Disneyland Park and Disney California Adventure Park. These provide quiet and private spaces to feed and change little ones.
Please return if you have any other questions. Have a Fantasmic day!
