2 seems to be correct if you are also trialing an ArcGIS Online organizational subscription. However; if you are an existing organization it appears that we actually get 5 seats for 15 days. I was only able to ascertain this by firing up the trial. 5 is much better for a large organization - however, its still very difficult to expose all of our interested users of D2M to the trial with a 15 day window. We are a government organization with users from many different business areas (each advancing in UAV technology at different times). It would be useful for us to be able to have multiple trial opportunities over the year (i.e. two or three 15 day trial opportunities would be better). A less appealing alternative is to tell our users to fire up their own AGO trial to access a 15 day trial.
