Rehearsal dinner

Hey everyone, so I’ve been receiving a lot of conflicting opinions on this topic and wanted opinions from those who are specifically planning their weddings and what they plan on doing/what they’ve done in the past. Should +1’s of the bridal parties be invited to the rehearsal dinner? Part of me wants them to come because it would be respectful to invite the people closest to our close friends, especially since we are planning on doing a destination wedding but the other part of me wants it to be more intimate between just our closest friends and family members, and a lot of our bridal/grooms party +1’s are fairly new relationships that we don’t know too well. My other concern is that a lot of the +1’s are extremely introverted, and I feel that they may be uncomfortable being around all of our family members they don’t know/would enjoy spending alone time at the hotel instead. Should I extend the invite to everyone anyway and they can decide whether or not to come, or should I limit it to just the bridal parties and family? Thank you guys!
