Wedding guests must navigate rising costs A wedding isn't just a huge financial commitment for those getting married. It can even be a pricey event for those on the guest list.While guests shouldn't be taking out loans to attend upcoming weddings, the cost for taking part in a wedding ceremony continues to snowball.
