You can extend the reach of your passes by purchasing Associate Countries. A month is counted as a calendar month. For example, a pass that begins on September 15 will expire at midnight on October 14. For the train it is midnight to midnight. For the car it is 24 hours from time of pick up.
More space is available for luggage.
On some specialty Premier Trains a meal will be included in the price for first class. The class of travel you choose depends on your budget and personal preferences. You will find that as the scenery changes from country to country, the personality of the trains change as well. Day trains could have either compartment seating or coach seating, or even both. With compartment seating, the car is separated into cabins which open to a corridor along one side of the car.
