see kids, Lily Allen is proof, you can go from being a drug dealer in Ibiza, to a musical star, and eventually play at coachella
I had no problems with my tent last year. The only thing that happened was someone else walked in on us when we were sleeping. This year I'm probably going to get a lock to put on it and obviously you don't want to keep anything of value in your tent. But you should be fine, no worries.
Just don't leave any valuable stuff in there, we had just one dude during the feast last year carry our stuff about when we weren't at the tent.
At least you guys have tents to get stolen =(
