I've never been to a casting call, however, I've been to tons of concerts and waited in lines for that! Get there as EARLY as possible, brings snacks, drink as little as possible.. everyone wants this, maybe see if they are starting a line the day before? And just think about the logic of who they want on the show, someone who can exercise and keep up with their crazy exercise schedule. Thats my best advice, oh and smile lots, personality is everything in life
Goodluck! I can't wait to hear all about it!
