Should I go on a vacation with my boyfriends family

I’m 19/f and my boyfriend is 19/m we have been dating for almost a year

We both live in Australia with our intermediate familes but the rest of his family live in Europe (England Paris and France)

I know his parents and brother very well as I stay over at their house every week and they’re lovely and we have a good relationship. They go and visit their family in Europe for 4 weeks around the holidays and I was invited to come along! I’ve always wanted to visit Europe but I’m worried about not being able to explore the beautiful cities and spend time with my boyfriend as he will be reuniting with his family (We will be staying at his family’s houses)

What should I do? Go with them or save my money for a more intimate holiday with my boyfriend
