"From the minute you walk into the promenade – because we're going to be playing amphitheaters during the summertime – it's going to feel like a whole other world," Kevin Jonas, 22, reveals to PEOPLE. "It's going to feel like you're going to camp. There's going to be things to do from the minute you walk in to the end of the night."
That's because the shows will include lots of music from Camp Rock 2: The Final Jam, which premieres Sept. 3 on the Disney Channel. Demi Lovato, who appears in the film, is joining the brothers on tour, and other Camp Rock stars will perform, too.
Kevin assures fans that the brothers will be doing their own songs as well as the Camp Rock music. "What we're doing is having our friends come out for songs that they are part of, and even Camp Rock songs," he says. "So, we'll do our set, we'll do everyone's favorite songs, all the hits, and then bring out Demi."
The tour is set to begin July 27 in Dallas and wrap Oct. 17 in Raleigh, N.C., after more than 45 North American shows. Stops are also expected in Latin American and Europe. Tickets go on sale May 15.
