At train shows, we (the Bay Area LEGO Train Club) have developed a standard city block system, where our downtown area is divided up into blocks that are 2 by 3 32 x 32 baseplates in size (i.e., 96 x 64 studs). For some time now I’ve shown my Blackburn Hotel and its accompanying city block (but I have never done a proper photo shoot of those buildings either, I just realized) at various shows and conventions and you have probably seen that featured here a few times.
