Pluto wants you to stay put on the Fourth of July!If you want to end your Fourth of July with fireworks at the Magic Kingdom or Epcot, plan to arrive early and stay. The Fourth of July is one of the busiest days of the year at Walt Disney World, and there’s a good chance that Park Hopping will not be allowed later in the day. If you decide to chance it, call the Park Hopping Hotline before heading out. The number is 407-560-5000.
