That's what your groomsmen and best man are for.
That is the truth. Most people think groomsmen and the best man just stand there, but fundamentally they are there to back you up on your big day. Most groomsmen don't realize it, but they are responsible for security in the event things go sour.
If some crazy ex-girlfriend kicked in the door of the church or rehersal hall, it would be the job of the groomsmen to deal with it and eject her, while you focus on your wedding.
Its your big day- you should be able to enjoy it and not be watching your six constantly like you're walking across a dark parking lot. If anyone should pack- it should be the groomsmen, not you.
