Disney-MGM Studios: Disney-MGM Studios will celebrate the Fourth of July with a special nighttime fireworks show at 9 p.m. Exploding in a kaleidoscope of color over the 12-story Mickey's Sorcerer's Hat icon, the showbiz-inspired, pyrotechnic performance will feature a choreographed soundtrack that combines traditional tunes with pop tributes. Fireworks again take center stage at 10:30 p.m. when Mickey Mouse stars in "Fantasmic!" -- the theme park's popular 30-minute show that features lasers, lights, dancing fountains and dazzling special effects.
