Event planners, do yourself favors and make your events fun for yourself and your community.
Build a gig bag with all the adapters, plugs, slide remote, etc. that you could possibly need to save the show.
The audience doesn't know the drama that happened behind the scenes, don't bring it with you on stage.
You set the tone of the room that your guests have to deal with. Be kind.
Be overly generous to the people working in the venue.
Say thank you and be grateful for everyone who took time out of their life to come to your event.
