You can only do it if you do a vow renewal at WDW or on the
Disney Cruise Ship. We are getting married on the Disney Dream and are having our photo shoot during our honeymoon while at Disney. For 2014 the price has increase, it's $1700 for just the MK, $2000 for MK plus another park and I think the other 3 parks are around the $900 range.
I hope this helps
