I'm the wedding host. I'm in the hotel every day, and usually I don't know any new people in the hotel. When you see a strange face, you won't ask any more questions. If someone really asks you, say it's from the wedding company, but pay attention. After going in, find a place to sit and talk less. See where the VIP table is. Don't take the wrong seat. Usually, it is best to put flowers in vases on the table beside the stage. Don't worry about being beaten on the big day.
