What do you think of my GF doing this?

Hey guys I got into my first relationship last august (UK). My GF basically want to go on a holiday with 2-3 other female friends and one bi sexual guy friend and they want to go to somewhere maybe like Spain or Greece (Europe basically) and they want to do normal holiday stuff and she also wants to go clubbing there. I already talked about how I don’t really like the idea of it and clubbing but she still wants to go as she’ll feel left out and she really wants to go on a holiday this year. She says she never wants to go clubbing in UK but she wants to abroad. I haven’t heard good things about clubbing for women and I’m not a clubber myself or a party person. What do you think and what should I do?
