Yes! We packed a book sack with water, Gatorade, & snacks. Just make sure all food & drinks are unopened until you pass through security. We also refilled our water bottles Throughout the day at the water fountains.

Yes, empty, reusable water bottles are permitted at both Universal Orlando Resort and Universal Studios Hollywood in 2026. This is a highly recommended "pro-tip" to save money, as bottled water inside the parks can be expensive. You can fill your bottle at any of the numerous water fountains or at the Coca-Cola Freestyle stations located throughout the parks (though these stations only provide free water and ice; you must pay for a special cup to access the soda). Universal also allows factory-sealed plastic bottles of water or non-alcoholic beverages, provided they are 2 liters or less. However, glass containers and metal cans are strictly prohibited for safety reasons. All bags and coolers are subject to X-ray or manual inspection at the security checkpoints. Bringing a lightweight, collapsible water bottle is often the best strategy, as it can be easily stored in your bag while you are on rides, ensuring you stay hydrated during the hot Florida or California afternoons without the "premium" theme park price tag.
