I'm writing a fairly massive space opera, with 4 POVs. One of them has 13 chapters, and in the span of those 13 chapters (which show just a single drawn out scene - there are no scene breaks within the chapter) one of the characters manages to visit 7 different planets. He is investigating something, and that's just where the story takes him. Still... I wonder if this is a little too excessive. Especially when 2 of 4 characters are on World A in the first 1/2 and then on World B in the second 1/2. The last character pretty much stays on World B the entire story. Is there something to be said for limiting the amount of setting changes for a single POV? I really don't want to eliminate any of this character's trips, but I feel I might be overdoing it.
