The "best" age is highly subjective, but many experts agree that ages 6 to 9 represent the sweet spot for a first visit. At this age, children are usually tall enough to meet the height requirements for almost all attractions, including "mountains" like Space Mountain or Tiana’s Bayou Adventure, yet they are still young enough to fully believe in the "magic" of character encounters and immersive storytelling. They also have more stamina to handle the extensive walking without needing a stroller, which simplifies logistics for parents. However, if you are looking for a "one and done" trip, waiting until age 10 or 12 ensures they will remember the experience for a lifetime and can handle the late-night fireworks and long park days with ease. Conversely, "pre-schoolers" (under 5) enjoy the park for free, but they may find the sensory input overwhelming and will likely not remember the specific details of the trip.
