Get ready to ‘Rock Your Disney Side’ during a 24-hour party at Magic Kingdom

This Memorial Day weekend, show your Disney Side during a bi-coastal event where Disney parks in California and Florida will be open for 24 hours.

The “Rock Your Disney Side Party” will take place from 6 a.m., May 23 to 6 a.m., May 24, local time at the Magic Kingdom in Florida and Disneyland and Disney California Adventure in California. Guests are invited to show their Disney Side and dress up as their favorite characters to the party.
