Whether you can wear a fanny pack (belt bag) on a roller coaster in 2026 depends entirely on the specific theme park's safety policy and the ride's restraint system. At Walt Disney World, fanny packs are generally allowed on almost all rides as long as they don't interfere with the lap bar or harness. However, at Universal Orlando and many Six Flags locations, strict "no loose articles" policies are enforced on high-intensity coasters like VelociCoaster or Iron Gwazi. On these rides, you must store everything—including fanny packs—in free lockers before entering the line. Some parks have metal detectors to ensure compliance. If the ride has a "bucket" or "pouch" on the seat, you might be allowed to keep it there, but for any ride with a chest-facing harness, you will likely be asked to remove the bag to ensure the safety restraint can lock properly against your body.
