Hi Jessica!
Welcome to planDisney! Thank you so much for sending your Disneyland Resort vacation planning question to us hEAR!
Oh Boy! Traveling to Mickey's house with your
Mouseketeers sounds like so much fun! I hope your family enjoys your
Southern California holiday! This is a quandary indeed. Disneyland Resort does not offer a shuttle between any of the LA area airports, however, hEAR are two very handy links that mention both
getting around the Disneyland Resort area as well as
transportation from the area airports. California does require children under the age of 8 years
or 4ft 9in tall to be in an appropriate car seat when riding in a non-commercial vehicle. (Rental cars, taxis, app-based ride-hailing cars, etc.) Larger commercial vehicles (busses, shuttles, trains) in the state do not have a car seat requirement.
I'm a military wife and I've been in your shoes many times as we've traveled around with our son. If your children are old enough for backless booster seats, you'll be able to bring those on the airplane cabin with you to store in either the overhead bins or under their seats. If your children are smaller and you've purchased seats for them, you should be able to bring those seats into the cabin for them to sit in on the plane. Definitely double-check with your airline about their rules when bringing seats on board. I've found that most taxi and Uber drivers are very understanding, too, when it comes to installing and uninstalling car seats from their vehicles and never felt a rush to get in or out. (Pro Tip: My husband still has a hard time putting one of our seats in our own vehicles, so be sure to pack the installation guide just in case you need it.)
Your best bets might be to either schedule a chauffeured car (like a town car or a limo) or a rental car from SNA and add car seats from that vendor. This might incur an extra rental fee, but at least you'll know that your
littles will be set. Both companies will monitor your incoming flight so should there be a delay they'll know about it auto
magically. And a super bonus of using a town car or limo is that their drivers can usually pick you up curbside or assist with getting your luggage.
I hope that this helped to better plan your upcoming vacation to
The Happiest Place on Earth, Jessica! Be sure to check out the
