I don't see the point of getting married at all, especially when you're royally screwed once you're divorced.
The best advice I have in the area is to consider what you want before you go out and get it. Where many people do not; you have the opportunity to chose something more specific before hitting the marketplace. (I can say more on this topic if there is interest)
