My girlfriend is going to be an actress in a hotel. I don't think those places are suitable for her! But she is too stubborn. what can I do?

Respect her choice. It is important for two people to respect each other's choices. After all, she just works as a showgirl and earns money by working. What happened? It's just that some people in society are biased against this, so there's no need to care too much about other people's eyes. This job is not for one person. Being able to do this job shows that your girlfriend has good conditions and no ideological burden. How many girls want to do it, but they can't because of poor conditions. If she wants to do it, you can be flower girl and stay with her every time, so that everyone and your girlfriend can obviously be taken, and generally no one will strike up a conversation. Find more hotel staff and let them handle it.
