We agree that GCT/OAT should add single page (8.5x11inch) maps to their Handbooks & Final Documents/Itinerary booklets.
These maps should be more detailed than those on the GCT/OAT website & in mailed sales brochures and in color, if possible. They should cover the route of the whole trip, and, if possible, additional detailed maps for key multi-day stops, e.g. Moscow, St. Petersburg, Kiev, Tallinn & Helsinki for "Russia Revealed".
We find it easier to understand the itinerary, history, sites, etc. of a trip with well written descriptions supported by maps. In many cases the map pictures can save words of description or at least improve our comprehension.
