Many times an organization will hire a comedian to speak at their annual dinner. They see them on a television show and assume that they will be just like their character they play on tv. They don't realize that sometimes the comedians material they use in there act is not rated "G" or "PG" but "R". This can get the organization in trouble if someone if offended.

For more on this read my column in George Gilbert's Motivational Humor entitled "Your Fired - Humor in the Work Place.

Make sure you ship all items for you conference 10 days before, so that you know they will arrive on time.   10 days prior to the event email all attendees a reminder of the conference you also want to confirm your speakers and other key guests.

Confirm all Travel and lodging arrangements.

Make sure you have enough time before to setup the room and enough time after to breakdown the room. Venues may book more than one event in the same room on the same date for different times. Some events are  scheduled too close to get into the room before you will have to rush to get the room organized the way you want it. this creates stress on everyone involved. Also you don't want to have to cut you meeting short because there is a group of people waiting to get in immediately after you are scheduled to be done. This also creates stress and can leave a bad memory on the event.

Confirm your venue. I have heard of events being double booked. There is nothing worse than having your event ruined because the venue booked two groups in the same room at the same time. By reconfirming several times in writing and over the phone you lessen the chance of having your event double booked. This also lessens the chance of the venue being closed.  

Make sure there will be someone there to let you and your party in. I recently was told of an event that was scheduled after hours on a Saturday. When the participants arrived the property was locked up. There was no way to get in and they had to move the meeting to someones house at the last minute. This created a lot of chaos and many participants didn't make it to the other location, because they either got lost or arrived after the group was moved and didn't find out about it in time.

Make sure you have the events contact information. Get every name and phone number available especially cell phones so that if your event is scheduled after hours you can still get a hold of someone to let you in.
