The short answer: your bag will be screened at the gate, several of the biggest rides won’t let you carry on a phone or bag at all, and outside food rules are different at almost every park — so pack a way to secure your valuables and check your specific park’s policy page before you leave home.
This guide covers the rules that are actually confirmed on park websites (Six Flags-family parks, Universal Orlando, and Walt Disney World), a plain checklist of non-gear essentials, and a short list of gear that makes following those rules easier.
Stats at a Glance
- Bags Allowed: Varies by park — expect security screening (metal detector or X-ray) everywhere; exact size limits differ, so check your park’s official site
- Loose Articles: Confirmed at Six Flags-family parks and Universal Orlando: phones, keys, hats, cameras, and bags must be secured in a locker or left with a non-rider for many major rides
- Outside Food: Varies widely: Disney World allows self-consumption food/nonalcoholic drinks (no glass, no heating needed); Universal Orlando limits it to bottled water (2L max) plus medical/dietary items; Six Flags-family parks generally prohibit it inside the gates but offer a parking-lot picnic area
- Lockers: Available near major rides at Six Flags-family parks, Universal Orlando, and Disney World — free vs. fee-based access differs by location, so check the official site
The Rules to Know Before You Pack
At almost every U.S. park, your bag gets screened at the entrance, and many of the biggest rides won’t let you carry on a phone, bag, or even a hat — you’ll leave it in a locker or with someone who isn’t riding. The exact rules differ by park and by ride, so the posted sign at the ride entrance (or the park’s own FAQ page) is the final word, not a blog post.
A few specifics are confirmed straight from park websites. At Six Flags-family parks — which now include Cedar Point and Kings Island — loose articles (phones, keys, hats, cameras, bottles, purses, and backpacks) aren’t permitted on rides and must go in a locker or stay with a non-rider, and outside food, drinks, and coolers aren’t allowed inside the gates, though most locations have a picnic area in the parking lot. At Universal Orlando, bags and suitcases with wheels and hard-sided coolers are turned away at security, soft-sided coolers are capped at 8.5 x 6 x 6 inches, and outside food is limited to bottled water (2 liters max per guest) plus items for medical or special dietary needs. Walt Disney World takes the most relaxed approach of the three: you can bring your own food and nonalcoholic drinks for your own group as long as it’s not in glass containers, doesn’t need heating or refrigeration, and isn’t strong-smelling — just mention it to the security team at the gate.

None of this gets you around a park’s rules, but it makes following them a lot less annoying.
Crossbody Phone Holster
On rides that allow a secured phone (as opposed to the handful of no-loose-item coasters), a holster strapped across your body keeps your phone off the loose-article pile without stuffing it in a pocket that can pop open on an inversion.
Two-Way Zipper Belt Bag
Small enough to clear most park bag checks, and on rides that allow a strapped-on waist bag, two zippers mean your card, keys, and phone stay shut through an inversion instead of in a pocket.
Waterproof Phone Pouch (2-Pack)
Log flumes, rapids rides, and splash zones are standard at almost every major park. A sealed pouch means a phone survives the ride, with a second one to spare for whoever else in the group forgot.
Disposable Rain Ponchos (Family Pack)
Six Flags-family parks and Universal Orlando both exclude outside food but not ponchos, and a pack in the bag beats paying gift-shop prices once an afternoon storm rolls in.
Anker MagGo Power Bank (10,000mAh)
Mobile ordering, ride-reservation apps, and all-day photos drain a phone fast — and if you’ve just retrieved it from a no-loose-item locker, you’ll want enough charge left to actually use the app.
Amazon Basics Cooling Towels
Bag-screening lines and shade-free queues both eat into a hot afternoon. A cooling towel is one more thing to soak and drape while you wait.
Packable Rain Jacket
Folds small enough to clear most bag-size limits with room to spare, so you’re not choosing between a jacket and everything else that has to fit in a locker or under a security size cap.
Quick Checklist
Beyond gear, these are the non-shopping essentials people actually forget.
| Bring | Why |
|---|---|
| Park tickets or mobile reservation | Needed for gate entry and often for ride-reservation systems |
| Photo ID | Required for will-call ticket pickup and age-restricted purchases |
| Payment card or mobile wallet | Many parks are cashless or cash-light at food and locker kiosks |
| Empty refillable water bottle | Most major parks allow empty bottles through security and have refill stations inside — confirm your park’s rule first |
| Broken-in, comfortable shoes | Expect several miles of walking between queues each day |
| Light rain layer | Afternoon storms are common in summer at most U.S. parks |
| Small amount of cash or a card for lockers | Lockers at no-loose-item rides are often fee-based |
| Sunscreen | Applied before you arrive and reapplied through the day, since shade in queue lines is limited |
Tips From Experience
Pack like your bag might get left in a locker for the length of one ride: keep ID, card, and phone somewhere you can grab in one motion, not buried under snacks at the bottom.
If a ride has a no-loose-item policy — common on launch coasters and anything inverted — use the free, ride-specific lockers near that entrance rather than carrying everything to a gate locker across the park; it saves a walk back.
Check your park’s outside-food rule before you pack a cooler. Showing up to a Six Flags-family park with a full cooler means a trip back to the car, while the same cooler is fine for a Disney World picnic lunch.

Theme Park Packing List: What to Bring to Any Amusement Park FAQs
Can you bring a bag on rides at theme parks?
It depends on the ride and the park. At Six Flags-family parks (including Cedar Point and Kings Island) and Universal Orlando, several of the biggest coasters don’t allow any loose articles — including bags, phones, and hats — so you’ll use a locker or leave items with someone who isn’t riding. Check the posted rules at that specific ride’s entrance.
Can you bring your own food into a theme park?
It varies. Walt Disney World allows outside food and nonalcoholic drinks for your own group as long as it’s not in glass containers and doesn’t need heating or refrigeration. Universal Orlando only allows bottled water (2 liters max per guest) plus food for medical or dietary needs. Six Flags-family parks generally don’t allow outside food or coolers inside the gates, though most have a picnic area in the parking lot.
Are theme park lockers free?
Policies differ by park. Universal Orlando offers short, complimentary lockers near many major attractions (long enough for one ride cycle) plus paid all-day lockers elsewhere. Six Flags-family parks and Disney World also offer lockers, but free-use duration and pricing vary by location — check your specific park’s official site.
What size bag can I bring into a theme park?
It varies by park. Universal Orlando’s official policy prohibits bags and suitcases with wheels and hard-sided coolers, and caps soft-sided coolers at 8.5 x 6 x 6 inches. Other parks set their own bag-size limits that aren’t identical, so check the official site for the specific park you’re visiting before you pack.
