Does Selectpass include travel within the same country? Will it be counted as 1 day, ex. Cologne to Munich or Paris to Versailles? Thanks!
Yes, you can travel within a country for which your pass is valid, but you will use a day of your pass in so doing. Don't waste a pass day for Paris-Versailles. A single Metro/RER ticket from anywhere in central Paris to Versailles-Rive Gauche costs €3.05 each way.
Thanks! That really helped a lot.
You're welcome! Update: I just checked eurail.com. A railpass will NOT cover your ride on the RER C to Versailles-Rive Gauche. The only thing it will cover in Paris is a ride on the RER B between CDG airport and Gare du Nord (which would also be a waste of a pass day).
You can actually travel for the entire day in all of the countries listed on your pass (eg, Munich to Paris would be one day).
