Totally, I say something like that in the last paragraph on the 1st page of the instructions, but it might have been better in the read-aloud text.  

You can totally share a scene on the map. You can also backtrack, have multiple characters with the same title, and keep playing after you reach the glow.

You are also correct that the locations with fewer Scenes are designed to push people along. But it is a soft push. Just that fewer scenes means that people will get tired of the location sooner. You’ll notice that these locations are more of the “traveling through a landscape” kinds of places. To give us some pause between the “experiencing a new culture” kinds of places.
