Hi Michaeleen! Thanks for visiting planDisney.
It sounds like you plan on having some luggage in tow today when you arrive at the parks. The good news is there are lockers you can
rent daily subject to availability, which hopefully will fit the bill. They come in several different sizes and are conveniently located in Disneyland Park on Main Street, U.S.A., Disney California Adventure Park on Buena Vista Street, and outside the Main Entrance of the parks.
If you're concerned about locker size, check out the larger-sized lockers outside the parks, which come in the following sizes: large (15” x 16.6” x 22.6”), extra-large (15” x 23” x 22.6”) and jumbo (18” x 25” x 37”). I hope one of those will be big enough to stow your bag while you enjoy the magic of the parks. Daily rental price is determined by the size of the locker and the prices are subject to change. You'll have access to the locker for the full length of the day but not overnight.
While Guests of one of the
Disneyland Resort Hotels can leave their bags with the Bell Desk if their room is not yet ready and they want to enjoy dining, the Downtown Disney District, the parks, and more, this is a benefit exclusive to those Guests with a hotel reservation. It will be closer for you to store your bags in a rental locker anyway since you won't be staying at one of the hotels. The lockers being located inside the parks or right outside is more convenient for your needs.
I hope this helps!
