ORLANDO (CNN) -

Three Disney World parks stayed open for 24 hours Friday to kick off the Memorial Day weekend.

Guests pulled all-nighters at the Magic Kingdom in Orlando, and at Disneyland and Disney Adventure parks in Ahaheim, Calif.

Each park had rides around the clock as well as special events and visits from characters.

Disney held a similar event in 2012 to mark leap year.
