Generally, business will be better on weekends, Saturday and Sunday, but it also depends on the location of this hotel. If it is in the core area, I estimate that business will be better every day.
As far as catering is concerned, generally speaking, hotels are weekends and holidays, and business will be better, because everyone has a holiday at this time, and sometimes they will go out to eat if they don't want to cook at home, while at work, it is not easy to go out, or they don't want to spend too much time tossing out, so there are relatively few people in the hotel.
