This document outlines 5 mistakes to avoid when working with event planners: 1) Don't be demanding, ask nicely for things. 2) Don't send planners on wild goose chases, have information ready. 3) Don't be late, planners appreciate clients who are on time. 4) Don't assume planners want to promote your products, ask them first. 5) Have a clear, concise contract and don't present planners with ambiguous terms.
