Disney Princesses Weddings

I just posted an RSS feed from Walt Disney World and it continues to make me think.  The feed shows several pictures of wedding displays that a woman can have, so she can feel like a real life Disney princess.  But again, what happens when the marriage doesn't work out, either in real life or in Disney?  In the movies no one ever talks about the price of the big extravagant weddings so girls grow up thinking they can have the same wedding, a girl can feel like Cinderella.  But what about in real life?  What happens when the girl who has dreamt of having a wedding like Cinderella finds out no one can afford it?  If the couple finds a way to pay for the wedding, how much strain is put on them an their new life?  Should girls be taught they can be like the Disney princesses we have grown up with, or should they be shown life after the story ends?  What happened to Cinderella after the wedding?
