Are the pits a good idea?

My husband and I want to go see a Simple Plan concert for the first time and are going to do the pre show VIP experience as well. My husband thinks the pit will be the best, but I'm not so sure. I heard if you do the VIP thing you might get in late to get a good spot in the pit. Also, I'm wondering, is the pit even a good spot for average or short people? Are people aggressive in the pit? I don't really want to be smacked.
