They can also send a call for more details, get attendees excited with a featured guests’ call, or just for a more personalized touch! And once guests leave, event planners can still reach out to their attendees. Send them a survey to find out how they liked the event – did they like the keynote, were the sessions informative, were the drinks tasty strong enough, etc? Guests can also be surveyed before the event to find out what attendees want to see or what their preferences are – chicken or beef?!
