We have a relatively large bridal party and all will be invited to the rehearsal dinner, obviously, with their significant others (and in the case of our flower girl and ring bearer, both their parents). In addition, we'd like to invite family to the rehearsal dinner since they're all traveling from out of town. But this makes up a good portion of the guest list. The place we're holding the dinner is a well-known restaurant close to the venue and I'm just wondering if other wedding guests (some from out of town) choose to go there the same night, would it be rude if they see us all there and they weren't invited?
Ideally, we'd host everyone who is from out of town, but it changes the RD guest list from around 35-40 up to 80ish if they all come so we wanted to keep it limited to bridal party and out-of-town family to keep costs manageable. Is this okay?
