there is no need to follow tradition for tradition's sake.

It's great to put together a day that everyone will enjoy, but keep in mind that they are there to celebrate the two of you. As long as you keep them fed and watered, they will be happy. With each part of the planning process, ask yourselves 'Is this something we really want? Will this element make our day more fun?'

There's nothing wrong with tradition. Just figure out which bits you really want and which bits you can cast aside. Your day will be so much more rewarding because of it.
