6. Independence Day Week
When is the 4th of July not busy, regardless of where you go? Some of the largest crowds of the year descend on the Disney World Resort for Independence Day, and as a result the resorts have some of their highest costs of the year this week. The temperatures have begun to hit the sweltering 90s and can even hit triple digits. Independence Day delivers the trifecta of high heat, high crowds, and high costs. This week is for hardcore Disney fans only.
