Are there any independent dressing rooms like toilets in five-star hotels, or are they all open?

This needs to be distinguished according to different departments of hotels and hotels. For example, the gym will have a separate dressing room and shower room, and the swimming pool will have a separate dressing room and shower room. If the guest is in the guest room, it must be a separate bathroom, so there is no dressing room. Generally, guests in this hotel are open, unless the fitness center is outsourced, that is another matter. If it is a dressing room for internal staff, it will be different. Basically, men's and women's dressing rooms are separated, and there will be no separate dressing rooms for single people. The internal dressing room is not open to the public. I hope it helps you. thank you
