FI's cousin got engaged recently. We were with his family this past weekend and she was talking about her wedding plans. She really wants an outdoor wedding, but it's also important for her to have a church wedding. Since she and her FI are both Greek Orthodox and the priest won't marry them outside, her plan is to have a small, immediate family only church wedding, then do a big outdoor ceremony with the big party the next weekend.
FI sees absolutely no problem with this. Neither, apparently, does anyone else in the family. I mentioned that people will want to see the real ceremony and her response was basically "my guests won't know which one is the real thing." I wasn't going to harp on it too much because a) she's newly engaged and excited and I don't want to ruin that for her and b) it's not my family. They're planning for 2018 so I'm kind of hoping she changes her mind.
