The categories for locations visited by River Song, Bernice Summerfield and Iris Wildthyme make sense for several reasons. The main of them: they provide non-trivial information that currently is not easily retrievable. The creation of these categories is consistent with similar categories created for the Doctors, given that each of the trio is the titular character of one or several series, explicitly named after them. Thus, their role in their respective spin-offs is equivalent to the role of the Doctor in Doctor Who-named series.

Consequently, it is reasonable to create Category:Locations visited by River Song, etc. for each of these three titular characters, complete with all the appropriate subcategories that already exist for the thirteen incarnations of the Doctor (pruning away subcategories lacking three members).

However, this decision should not be construed as a blanket ruling affecting every character who visited three locations in their life, which after all applies to almost everybody. While there is no harm in adding three leads to thirteen Doctors, swamping category lists with dozens of longish category titles like Category:Planets visits by Blon Fel-Fotch Passameer-Day Slitheen would make bottoms of the pages significantly less readable and, hence, less useful. In general, creation of such categories should better be decided on a case by case basis.

It should be noted that at the moment we know of much fewer travels of River than of Benny or Iris. This should not be viewed as a reason to wait with categories for River until she catches up. Rather, it gives us an advantage as the more she travels, the more effort will have to be put into creating her categories from scratch.
