My partner and I are getting married in July. The week after we sent the invitations, my partner's sister died. At the funeral he found out that his family had decided to "bring closure" to their grieving by ALL of them coming to our wedding (we had only invited his siblings). We are now looking at 20-30 extra guests (@ $150/head). They had already made their travel plans before they mentioned anything to my partner.
I don't know some of these people. My partner doesn't know some of them (the count includes boyfriends, girlfriends and people who just want to come to Maryland). This is not a same-sex wedding issue, but it is a delicate one, as my partner's family is still grieving, so it is not like picking up the phone and saying "The invitations said +1 not +the entire family".
Should we suck it up and max out the credit cards to cover the extra guests?
