Walt Disney World balloons can be hard to say no to, especially when traveling with children! If you’re flying, you will not be allowed to take an inflated balloon on the plane. Head to the Disney Store at Orlando International Airport, and they’ll deflate it for you. Warn the little ones about this ahead of time, because it can be traumatic if they don’t know what is going on. You can most likely have it blown up again at home at any store that sells helium balloons.
