Hey there Sabrina,
Welcome to planDisney and thank you for your question! I'm happy to hear you're thinking about taking a trip to the Disneyland Resort.
You can certainly bring a backpack or fanny pack into the Happiest Place on Earth and they do not need to be clear. In fact, I almost always bring my backpack in when visiting the Disneyland Resort with my family. It's a great way to bring in snacks and water to sustain you between trips on the
Matterhorn Bobsleds,
Space Mountain, and
Big Thunder Mountain!
I would recommend taking a look at the
Park Rules and Regulations page to get a better idea of what you can and cannot bring in with you. Also, keep in mind that any bags you bring in will be searched when you enter the security checkpoint.
Stroller rental pricing is always subject to change but as of the time I'm answering your question, a single stroller is $18 and a double stroller is $36, both of these prices are per day.
Locker rental pricing is similarly subject to change at any time, but currently, lockers inside the park are $7 and $10 or outside the park are $7, $10, $12, and $15. The different prices of the lockers are subject to their size, so the larger locker options are located just outside the park.
These were great questions, Sabrina - keep them coming! We here at planDisney would love to help as you continue to plan your trip. Thanks for stopping by!
Have a Magical Day,
Greg
