What does The Cloisters’ staff do at my event? First, they oversee the set up to make sure you, your caterer and your decorator are abiding by Cloisters’ rules and regulations. Then, they help your guests to park. During the event they will float around, checking into safety issues, making sure the bathrooms are supplied and clean, and directing guests to the bathroom. Near the end of your event, they will make sure the bar closes down one-half hour before the scheduled end of your reception and they will oversee the caterer putting away the tables and chairs and cleaning up.
