Hi Matt,
Welcome to planDisney! You sound like my kind of planner and packer, and I'm so glad to hear you're thinking ahead and planning for protection in the beautiful California sunshine!
I'm happy to let you know that there's nothing in the
park rules that prohibits aerosol sunscreen, so you'll be able to bring that with you for your visit. I know that sunscreen is just one small item, but if you happen to have more with you than you'd prefer to carry all day, please feel free to take advantage of a
locker rental. On the visits where I just can't quite fit everything I need into a small bag like Mary Poppins, they come in quite handy!
Thanks so much for visiting us at planDisney, Matt, and please come back and see us any time you have a Disney-planning question or would like advice about any aspect of your visit. I hope you have a truly magical
Disneyland Resort adventure!
Missy
