In all seriousness, I made my wedding vows years ago and I am stuck with them.
Going to Las Vegas and getting Married by Elvis Presley is all good fun but you can never take away the first time you made those vows.
They do not need reinforcing in my view.
Just go and pay the money, get a nice photo and have a good time.
I have been an observer at a couple of weddings and the Las Vegas ones are fun.
