Lou,
Its your wedding day! Do it for you & your hubby!
You can have a small blessing when you come back from Vegas to appease the families, but utimatley its your day, so they will all have to deal with it.
Don't let the stress or emotional black mail get to you!
Show a united front with your hubby and both families will have to accept it.
Good luck & congrats again!
