Planning context
Begin with Premier France when the destination is not settled.
Use the country guide to compare trip shape, nights, transport, and the role of each possible base. It is the fastest route when several regions are still competing.
Once one destination clearly fits, continue to its guide rather than repeating the same comparison.
Use destination guides for practical depth.
Paris Guide handles the capital. Loire Valley focuses on chateaux, towns, wine, and transport. Dordogne covers caves, villages, rivers, and rural bases. Aix covers the city and a controlled Provence reach.
Each guide can therefore answer a smaller question with more useful context.
Return to the country guide when the route changes.
If a second base, no-car constraint, or shorter schedule changes the plan, return to Premier France and compare again.
The aim is not to visit every guide. It is to use the smallest number of guides needed for a coherent trip.
