RoadTrip - RoadShow - RoadShowCase

What's the difference between a RoadTrip, a RoadShow, RoadShowCase?

RoadTrip...

The "Trip" is a "scouting" prelude to meet potential sponsor-Ambassadors, to visit locations, and preview sites when appropriate. 

RoadShow...

The "Show" is normally conducted at Conferences or with intact work groups where a common workforce thread unites those in attendance. 

RoadShowCase...

The "ShowCase" is normally conducted at a location where many different workforce members come together from a variety of organizations to sample the workshop atmosphere and learn what programs in their organization might benefit.
