This seems to be a touchy topic, but I can't find another message board with my exact situation, so here goes ...
My fiance and I are having a mid-size destination wedding (75 people or so) that is within an 8-hour drive for most people attending. Our bridal party is 7 people (3 bridesmaids, 3 groomsmen, officiant). We rented a beach house next to our venue that will accommodate everyone in the wedding party in addition to those who had a significant other at the time (2 significant others out of the whole wedding party). We are now about 3 months out from the wedding, and some single people in our wedding party are going on Tinder dates with the intent to find someone to bring to the wedding. One of the groomsmen, in particular, messaged me and told me he was planning on bringing a date and having them stay in the beach house.
I feel it's important to note that everyone in the wedding party is either a family member or very close friend who knows everyone at the wedding and WILL have a travel companion.
Should I allow members of the bridal party who are single to bring a random plus one whom I've never met and allow them to stay in the beach house for 5 nights? The house is a decent size but only has 3 bathrooms, so having that many people in the house is a stretch.
Any helpful advice is welcome!
