140-Disney-Character 'Ultimate Tweet' Announces All-Night Disney Side Party On Both Coasts

The underlying "joke" here is that, when you tweet a tweet on the Twitter website, the tweet can only be 140 characters (alphabet letters, numbers, and so forth) or less.

So, to announce their 24 hour “Rock Your Disney Side Party,” the Disney parks had 140 Disney characters form into the well-known Twitter "hashtag" (#) formation and then posted it on Twitter. The party is set to be a fun-filled 24-hour event at both Disneyland Resort in California and Walt Disney World Resort in Florida, featuring Disney heroes and villains from 6 a.m., May 23 to 6 a.m., May 24, 2014 (local time).
