ORLANDO, Fla.- Walt Disney World is ending its annual Grad Nite festivities for high school seniors after this year because of concerns about scheduling and handling extra spring attendance at the theme park.

Officials at the park announced the news on the Disney Parks Blog Wednesday, saying the increased spring attendance has made it difficult to schedule the separate-ticket, after-hours events. The four Grad Nite dates in April and May will take place as scheduled.

Grad Nite is in its 40th year at the Florida park and in its 50th year at Disneyland in California. Disneyland will continue to hold Grad Nite.

Disney World will offer Florida school groups a one-day, one-park ticket for $55 as a future alternative. The special passes will be valid any time during the year.
