It's lights out for Disney World's Grad Nite.
The annual after-hours event for high school seniors ends with Saturday's last bash for the Class of 2011. It has become a rite of passage for students, who take over the park for late-night concerts, rides and other events especially catered for them.
Grad Nite began in 1972, shortly after the Magic Kingdom opened. Disney officials say the company will offer Florida schools a "Disney Senior Class Trip" next year _ a special one-day, one-park ticket for $55 valid any time.
Over the years, Grad Night performers have included New Kids on the Block, the Backstreet Boys, Britney Spears and Destiny's Child.
Officials say the Grad Nite at Disneyland in California will continue.
