Thoughts on inviting non wedding party person to bachelorette weekend?

I always just thought that the bridal party goes to the bachelorette weekend and no one else, but when I went to a bachelorette party for another friend she also had a few other non party friends come out with us for the night on the town and it was so fun! I mean she only had 3 bridesmaids and there were like 8 of us total going out with her.


I have 7 bridesmaids and I wanted to go to Vegas for a weekend trip and I’m wondering if it would be weird or faux pa to invite any other people? My work bff expressed interest in going (kinda like a joke, but I know she would be really fun!) and now I’m thinking of inviting her to go but I don’t want it to be weird with my bridal party since they don’t know her? Should I just leave it as is with only my bridal party and not even think about this idea? What do y’all think? I’m still inviting her to the wedding too.
