Joe Jonas and Demi Lovato will be performing a private concert at Walt Disney World’s Epcot theme park on February 11, 2010 for a Celebration of Volunteerism event. The Radio Disney Spirit of Volunteering Sweepstakes has already closed, but no word yet on who won the grand prize of a 4 day / 3 night trip for four to the Walt Disney World Resort to watch Joe and Demi’s performance. Is anyone planning on attending the concert at Walt Disney World on February 11th.
