What about experience?

​The event you are planning may be a onetime affair or it may only occur once each year.  It may be the only time you have booked entertainment for an event.  Although the process may be unique for you, an experienced entertainer does events like yours all the time and knows how to make them a success. If not, they wouldn’t be in business.  Look for acts that regularly perform at events of the type you are planning.  Experience does matter.
