Bachelor party question

Is it me or it is a bit weird that 1 chick goes to a 3 days bachelor party away with 18 guys with her being the only girl?

I mean, she is a very good friend of the groom to be but still?? Couldn't she just got to the wedding?

There are gonna be strippers and what not, I would find myself a bit uncomfortable I guess.

(It's not my fiance, it is one of his best mates. I'm not jealous or anything about her being there, I just wonder if anyone else find it strange🤷🏻)
