In 2026, the consensus among Disney regulars is that 6 is not too old for a stroller, though it is a transition year. A typical day at Walt Disney World involves walking 8 to 12 miles in high humidity, which can be exhausting for a 6-year-old. While many children this age don't use strollers at home, the "Disney Mile" is different. Using a stroller provides a mobile "safe space" for naps, shade from the sun, and a way to move quickly between attractions without meltdowns. Disney's 2026 guidelines allow strollers up to 31" wide and 52" long, but remember that stroller wagons are prohibited. If you're hesitant to bring your own, Disney rents single strollers for roughly $15 per day (recommended for children up to 50 lbs), which is a small price to pay for preserving your child's energy—and your own sanity—during a long "rope drop to fireworks" park day.
