Installation & Dismantles, better known as I&D's.  This is a part of your trade show experience that you really need to focus on when it comes to the cost of getting your exhibit in & out of the convention you are attending.  Having the right company that can handle the transportation, setting up & taking down of your display will make your life much less stressful.  When purchasing a larger display or a display any size that is hard to set up, be sure to find out what it will take to set up and if it is worth it to you to use a trade show I&D company.
