The hotel has hosted a dinner party, can the same hall still host a luncheon?

Yes.

It can be held at noon or in the evening, depending on the local customs and habits. In many northern areas, banquets are held at noon, while in the south, banquets are mostly held at night.

In many northern areas, wedding banquets are held at noon. They believe that sufficient sunshine at noon can ward off bad luck, so it is better to get married at noon, while the evening represents the second marriage. On the contrary, many southern areas are accustomed to holding wedding banquets at night. For wedding banquets, this is a more traditional time for marriages, because the ancients believed that dusk, when day and night alternate, is the moment when yin and yang come together, which is the most suitable time for marriage.
