Greetings, Brittany, and welcome to planDisney!
I'm so happy to see you here and thanks for bringing your question to us! I'm old enough to remember when Disneyland Park used to have a dedicated picnic area just outside the Park for Guests. My grandmother would bring an entire cooler packed with lunch for our entire family when all I wanted was to enter the Park and get a churro!
Most of the items on your list seem just fine, including food and drink (with the exception of alcohol). The Disneyland Resort has a list of
Prohibited Items that are not allowed through security and I would recommend taking a look at this list to make sure that you are in compliance. Keep in mind that stroller wagons are not allowed, and
strollers must be less than 31" in width and 52" in length. And if by saying "scooter" you mean an
Electric Conveyance Vehicle (ECV), that is definitely allowed. You will see many of these throughout the Parks.
I think it's a great idea to bring snacks and drinks with you into the Parks to keep your energy up during a long day! We like to bring refillable water containers to keep hydrated as well. You can view available
water bottle filling stations throughout the Resort in the
Disneyland Mobile App. If you are on the go and need a fresh and healthy snack, there are
Fruit Carts spread around both Parks. At Disneyland Park, I often like to purchase a skewer at
Bengal Barbecue to eat on the go as a snack too!
Brittany, I hope that was helpful for you in planning your visit to the Happiest Place on Earth! If there is anything else that we can do for you, please do not hesitate in asking! We're here to help.
Have a Magical Day!
