Hello Everyone!
We are having a destination wedding in Las Vegas, so all guests will be coming from out of town. We have a pretty standard size wedding party (5 bridesmaids, 5 groomsman, 1 flower girl, 4 parents, 2 grandmothers). Four of the wedding party members are dating people who are invited to the wedding. One of them is my cousin's boyfriend who I am very close to. The other 3 girls I am not close to and honestly do not care for. All of these significant others know guests who are not in the wedding party and who are not invited to the rehearsal dinner. (Ex: Groomsman's sister is invited to the wedding and is very close the the girlfriend. So they can hang out while the groomsman is with us)
Do I have to invite the significant others to the rehearsal dinner? Or can I just have my wedding party there and then let the SO's know they can meet us afterwards for drinks? (Since it's not like they will be alone in the hotel room waiting around)
