Why do hotels charge admission fees for weddings?

The etiquette company that cooperates with the hotel should give the gift to the hotel. You don't need a etiquette company with a hotel license to collect gifts from you to ensure its expected income. Etiquette companies also use this mode of cooperation with hotels to attract business and crowd out competitors. Of course, it will indeed cause certain expenses to the hotel, such as electricity and cleaning fees. It is reasonable to charge some fees within a certain reasonable range, but it is unreasonable to charge too much. There is still room for discussion before the wedding banquet is confirmed.
