Why does it all look so cheep?

I was snooping and got a little confused. Both familys have money (his family def more then hers) but it feels like they didnt spend money on the wedding?? Youre telling me the best they could do is a little bath & tennis club? Her inlaws took the family on a $65k a week yatch trip but her mom ran around Jersey picking up wedding decor from facebook marketplace? Make it make sense.
