Starting December 1st, 2016 the Atlantic Dance Hall at Disney's Boardwalk Inn Resort could begin themed nights three days a week at the nightclub. The speculation is that on Tuesday nights the theme will be the 1990s, on Wednesday nights the theme will be the 2000’s, and on Thursday nights the theme will be Electronic dance music (or EDM). This news hasn’t been officially announced by Disney and is still considered a rumor. Currently the Atlantic Dance Hall is an extremely unpopular nighttime location on Walt Disney World property, so this could be an attempt to get guests inside.
Update: According to orlandoparksnews.com this news has been confirmed. Additional news from the official release says that the themed nights will be from 9 p.m. until 2 a.m. during the month of December. There will be no cover charge, and guests must be 21 and over.
