Long distance relationship vacation?

I met my boyfriend during my exchange year in another country. we are going to meet in a few weeks because I am visiting him. We‘re going on vacation in his country. I‘m really looking forward to it, but now he told me that his friend also has a long distance relationship and his girlfriend is going to visit him during that time as well. he asked me if it is okay if they come with us. I don‘t know how to feel about it, because I don‘t know them and I just want to spend time with my boyfriend. but I don‘t want to be rude and maybe I should just say yes and it will be fun? what should I do?
